MRI for multiple sclerosis -

As they relax, the protons release signals that are transmitted to a computer, analyzed and converted into an image. MRIs for detecting demyelination and diagnosing MS MRI is particularly useful in detecting central nervous system demyelination — that is, damage of the myelin sheath in the nervous system.

You may not always see a direct correlation between the MRI scan and your symptoms. Lesions seen on MRI may be small or have caused little damage. Your brain may have developed a workaround. Generally, lesions in smaller areas, such as the brainstem, the spinal cord or the optic nerve are more likely to produce signs and symptoms.

People over age 50 may have small areas on their MRIs that resemble those seen in MS but are actually related to the aging process. A similar thing happens with people who experience migraine headaches.

MRIs for assessing risk after clinically isolated syndrome CIS diagnosis MRI is particularly helpful in people who have had a single demyelinating attack that is suggestive of MS, also called clinically isolated syndrome CIS. The number of lesions on an initial MRI of the brain or spinal cord can help assess your risk of developing a second attack in the future and being diagnosed with MS.

Some of the treatments for MS have been shown to delay a second episode in people who have CIS. The MRI can also be used to identify a second neurological event in a person who has no additional symptoms.

This helps confirm an MS diagnosis as early as possible. MRIs for tracking disease progress After an MS diagnosis, MRI scans help healthcare providers track the progress of the disease and help you make the best treatment decisions.

Although GBCAs can be helpful, there are some risks to using them that you should know about: People with poor kidney function have increased risk of developing nephrogenic systemic fibrosis NSF if they are given GBCAs.

This rare and serious disease causes thickening of the skin and damage to internal organs. Small amounts of the GBCAs can stay in your body for several months to years. It is not yet known if this retention of GBCA is harmful. What you should know about these risks: The FDA issued a safety communication on the use of GBCAs and recommended types of gadolinium less likely to be retained in the body.

The FDA also required the makers of gadolinium contrast agents to do research to determine if GBCA deposits are harmful. What you can do: Ask your doctor if you need to receive GBCA for your next MRI scan.

It is not needed for all MRIs. Have your doctor check your kidney function with a blood test prior to receiving GBCA. This will reduce the risk of developing NSF. Most conventional MRI machines are 1. Open MRIs are usually less than 1.

The pattern and evolution of MRI lesions, in the appropriate clinical setting, has made MRI abnormalities invaluable criteria for the early diagnosis of MS. The first important role for MRI in the diagnosis of MS allows for an early diagnosis of MS for CIS patients using the IP diagnostic criteria, including MRI for dissemination in space DIS and time DIT.

The MRI evidence required to support the diagnosis varies, depending on the strength of the clinical findings. Allowing a new MRI lesion to substitute for a clinical attack doubles the number of CIS patients who can be diagnosed as having MS within 1 year of symptom onset.

Increasing the sensitivity of the test with more lenient criteria, as recommended by the AAN subcommittee, can result in decreased specificity. The second important role for MRI in the diagnostic work-up of suspected MS patients is to rule out alternative diagnoses obvious on MRI, such as spinal stenosis and most brain tumors.

Characteristic lesions that favor MS include Dawson Fingers, ovoid lesions, corpus callosum lesions, and asymptomatic spinal cord lesions. Learn more about SPMS here. MRI scans do not use radiation. The technician obtains the scan using a large, tube-shaped magnet. Various types of MRI scans can monitor MS activity in the brain.

Healthcare professionals can carry out different types of scans during the same MRI session. T-1 scans can involve the use of gadolinium, which is a contrast dye, to look for new or growing lesions. Permanently damaged areas of the brain appear as dark spots. These are also known as black holes or hypointense lesions.

According to some researchers , chronic active lesions are very damaging to the brain. These lesions require treatment as early as possible. A T-1 weighted scan without contrast dye can show hypointense lesions, which may indicate areas of permanent nerve damage.

New MS lesions appear as bright spots on a T-2 scan. These are also known as hyperintense lesions. Typical lesions that appear on a T-2 scan are oval in shape. Fluid-attenuated inversion recovery imaging reduces interference from the spinal fluid to help view the effects of MS.

Anomalies remain bright, while normal brain fluid looks dark. Spinal cord imaging can show that damage has occurred in different parts of the central nervous system at different points in time.

Learn about radiology tests for MS here. Radio waves then pulse through the body, causing the protons to spin out of order. Once the technician turns the radio waves off, the protons fall back to their original order.

As they return to their original positions, the protons release signals that transmit to a computer. The computer then converts these signals to detailed 2D and 3D images of body tissue and organs.

Before undergoing an MRI scan, a person needs to remove any clothing or personal items that may contain metal. The MRI machine makes loud knocking noises during the test. A person undergoing a scan will receive earplugs or earphones to help muffle the noise.

Gadolinium is a substance that forms the base of contrast dyes. It can only enter the brain if there is active inflammation. Inflammation from a new MS brain lesion breaks down the blood-brain barrier, allowing the gadolinium to leak into the brain.

Any gadolinium deposits that healthcare professionals find on an MRI scan suggest that there is disease activity in the brain.

The body almost completely clears gadolinium from the central nervous system after 48 hours. Healthcare professionals use MRI scans to confirm a suspected diagnosis of MS. The first MRI scan helps serve as a comparison scan, especially in evaluating CIS. A person with MS may expect to have routine monitoring of their condition every 3—12 months.

The frequency at which a person should undergo scans depends on the following:. MRI scans use strong magnetic fields and radio waves to create detailed images of the central nervous system in individuals with MS.

It is a safe and noninvasive test. Healthcare professionals typically use MRI scans to both diagnose MS and to help monitor how a person responds to treatment. For resources, research, and news for people living with MS, visit our dedicated MS hub.

No single test—including tissue biopsy—can provide a multuple diagnosis of MS. Therefore, over sclerosiis past 20 years, the neurological community multiplf adopted various diagnostic criteria, which have been modified as new evidence mulfiple expert recommendations have emerged.

The current diagnostic criteria for MS are based on the Liver Healing Strategies of lesions within the Sclfrosis that demonstrate dissemination in space DIS and fr in time DIT.

Additionally, the diagnostic criteria require exclusion of Achieving optimal blood pressure goals diagnoses that can mimic MS either xclerosis or radiologically. Furthermore, MRI findings can replace certain clinical criteria in Organic pet care substantial proportion scleosis patients.

Inthe International Panel on the Diagnosis of MS presented an evidence-based revision of the McDonald criteria. Cranberry pie recipes revised version increased the Energy-boosting womens health supplements of the critieria Insulin sensitivity and insulin sensitivity factor value simplified the features of both DIS and DIT, while maintaining the Hormonal balance benefits of the earlier sclrosis versions multiplw the criteria Table 1.

These new criteria have wclerosis received some criticism. The simplified and less-restrictive conditions in the last revision of the McDonald criteria fkr ultimately umltiple diagnostic specificity, thereby leading to overdiagnosis.

Cerebrospinal fluid CSF testing Proper nutrition for injury prevention support the MIR of relapsing MS is no longer required by the criteria, but CSF findings dclerosis be relevant in certain patients, particularly those for whom MRI is not entirely diagnostic or reveals features that are unusual in MS.

Undoubtedly, the McDonald criteria have substantially improved the diagnostic process in relapsing—remitting MS RRMSbut they exhibit a number of limitations in primary progressive MS PPMS. Paraclinical support of the PPMS diagnosis can be based solely on brain and spinal cord MRI findings.

The McDonald MRI criteria should be applied in patients with clinically isolated syndrome CISdefined as a first subacute or acute episode of clinical symptoms suggesting an inflammatory demyelinating disorder.

The criteria should also be used in patients with an insidious progressive neurological condition suggesting PPMS and MRI findings with features consistent with MS lesions 7. Application of the McDonald criteria can potentially result in an easier and earlier MS diagnosis than is achievable with older criteria 7.

MRI scans should be interpreted by experienced readers who are aware of the patient's clinical and laboratory information, and who are capable of fully assessing the evidence for and against a diagnosis of MS. The revisions to the McDonald criteria were partly based on findings from the MAGNIMS group in white European adults, 1112131920 but the International Panel considered that the new criteria were also applicable to the diagnosis of MS in other populations for example, paediatric patients, people of Asian ancestry, and Latin Americans.

However, the Panel emphasized the need to confirm this view through additional studies in these populations. One such study retrospectively evaluated the and McDonald criteria in a cohort of children with acute demyelination who had been observed prospectively for at least 24 months.

The findings from a multicentre retrospective study also supported the high diagnostic value of the criteria in children.

Recent data indicate that once neuromyelitis optica NMO and NMO spectrum disorders have been excluded, the accuracy of the McDonald criteria in patients with CIS is similar between people with Asian and European ancestry. This finding suggests that the presentation of MS in Asian populations does not fundamentally differ from that in white populations.

The McDonald criteria can be used in children older than 11 years if they do not show ADEM-like symptoms 21 These criteria can also be applied in patients with Asian ancestry, after NMO and NMO spectrum disorders have been excluded Further studies are required to validate the criteria in other populations, particularly Latin American and African American patients.

Follow-up brain MRI is required in patients who show clinical and radiological findings suggestive of MS, yet do not fulfil the McDonald diagnostic criteria. The interval between the baseline and follow-up scan is a matter of debate, but we suggest that the optimal interval is 3—6 months.

These time intervals could also apply in patients presenting with radiologically isolated syndrome RIS. New active lesions in patients with RIS substantially increase the risk of subsequent MS-related clinical events, 26 although a definite diagnosis of MS cannot be established in the absence of related clinical manifestations.

The value of repeating spinal cord MRI to establish the MS diagnosis is uncertain, but the available data suggest that it is limited. Follow-up brain imaging 3—6 months after the baseline scan is recommended in patients with CIS who have an abnormal baseline MRI scan but do not fulfil the McDonald diagnostic criteria If the second brain scan is inconclusive, a third can be acquired 6—12 months later In patients with RIS, a follow-up brain scan 3—6 months after the initial MRI is also recommended Follow-up spinal cord MRI in patients with CIS, to demonstrate DIS and DIT, seems to have limited value and should not be routinely performed 19 Histopathological findings and MRI data have indicated that diffuse and irreversible tissue damage occurs in the early stages of MS.

Timely detection of this damage could help identify patients with an increased risk of developing severe disability and cognitive impairment; these patients in particular might benefit from prompt, aggressive treatment. Conventional MRI techniques, such as T2-weighted and gadolinium-enhanced T1-weighted sequences, are highly sensitive for detecting white matter plaques.

However, these techniques are not specific enough to detect tissue damage within focal lesions, and they lack the necessary sensitivity for revealing diffuse injuries in both grey and white matter.

Huge efforts, involving the use of advanced MRI protocols, are being made to overcome these limitations. One of these advanced approaches is proton magnetic resonance spectroscopy 1 H-MRSwhich has been used in patients with CIS to identify tissue damage apart from the visible T2 lesions.

Substantial reductions in N -acetylaspartate a marker of neuroaxonal damage and increases in myoinositol a marker of glial cell activity have been recorded in the normal-appearing white matter of patients with CIS.

Importantly, the magnitude of these effects is highest in those patients who subsequently convert to clinically definite MS. Although these advanced applications of MRI can provide information that might be useful for estimating the risk of MS, the sensitivity and specificity of these methods for diagnosis and differential diagnosis of individual patients remain to be determined.

Various advanced MRI techniques have been used to differentiate MS from other inflammatory—demyelinating diseases with similar MRI features but different clinical courses, prognoses and treatments.

These methods have shown that ADEM, NMO and Leber optic neuropathy are associated with less diffuse tissue damage than is typical of MS, and this factor could be used as a distinguishing feature.

The currently available evidence is not sufficient to support the use of advanced MRI to establish the initial diagnosis or differential diagnosis of MS in patients with CIS. Early results suggest that advanced MRI can predict disability progression and cognitive impairment in individual patients, but confirmation is needed.

The McDonald criteria require symptomatic lesions to be excluded from the lesion count in patients presenting with brainstem or spinal cord symptoms. Thus, this criterion is difficult to implement, particularly when more than one lesion is present in a characteristic topography.

In a similar requirement, DIT can only be demonstrated by the simultaneous presence of asymptomatic gadolinium-enhancing and gadolinium-nonenhancing lesions, which probably limits the sensitivity of the criteria. Gadolinium-enhancing lesions represent new, currently active lesions, whereas nonenhancing T2 lesions are older lesions.

Thus, the DIT criteria should be met when both types of lesion are detected, regardless of whether they are associated with symptoms.

Therefore, removal of the prerequisite that only asymptomatic lesions should be considered for demonstrating DIS and DIT would facilitate use of the McDonald criteria and increase their sensitivity, though with a slight potential reduction in specificity.

Therefore, the presence of black holes in scans of patients with CIS could indicate an advanced disease course, and might be an appropriate proxy criterion for DIT. Although these lesions are common in patients with CIS, it should be noted that they have no value for predicting conversion to clinically definite MS.

Despite the fact that MRI has become a key tool in the diagnosis of MS, many imaging abnormalities seen in patients with MS are not specific to the disease. The McDonald criteria have become less restrictive over the successive revisions, which might eventually lead to the undesirable situation of overdiagnosis.

The perivenular distribution pattern and the suggested increase in iron deposition within MS-related lesions are potential targets for differential diagnosis. Recent experience with SWI on 3.

These hypointensities probably represent free radicals or iron deposition from several cellular sources that are present in the lesions, although myelin loss might also contribute to the signal abnormality. Another strategy for differential diagnosis is to include other important aspects of MS pathology, such as cortical abnormalities.

Cortical lesions are abundant in patients with MS, and are readily detected with pulse sequences such as double inversion recovery DIRwhich can selectively depict grey matter by suppressing signals from white matter and CSF.

DIR improves the sensitivity of MRI to detect cortical lesions in vivo62636465 although it has shown low interobserver concordance, particularly for the detection of pure intracortical lesions, thereby limiting its value in clinical practice.

However, these results should be confirmed in multicentre studies before modifications are made to the DIS criteria. It has also been suggested that intracortical lesion detection in patients with RIS could provide additional support for attributing subsequent incidental white matter findings to the spectrum of demyelinating diseases.

Despite these promising findings, imaging of cortical lesions at standard clinical field strength is suboptimal—even when combinations of sequences are used—because of limited sensitivity and reproducibility.

A simplified, less ambiguous definition of DIS is probably required A patient should be able to meet the DIT criteria regardless of whether the lesions are symptomatic Nonenhancing hypointense lesions on T1-weighted images have no value for predicting conversion to clinically definite MS when added to the current DIS criteria DIR, PSIR and high-resolution MPRAGE sequences increase the accuracy of MRI detection of intracortical lesions, and could be used as add-on sequences if multicentre studies confirm their value 6263646567 Further studies are needed before intracortical lesion detection, the 'central vein sign', and the susceptibility signal within lesions can be incorporated in the diagnostic work-up of MS at standard field strength 61 Standardization of optimized diagnostic protocols across centres is an important objective, as it would enable uniform performance and interpretation of MRI studies.

However, variations between centres in the available equipment hardware and software and data interpretation methods, and the need for validation of adapted or novel MRI sequences, are barriers that must be overcome to facilitate standardization.

Brain MRI is important for achieving a prompt, accurate diagnosis of MS, because of its high sensitivity for detecting white matter plaques Figure 1. However, several factors related to MRI examination—including patient positioning, the choice of pulse sequences and pulse-timing parameters, spatial resolution, coil technology, contrast medium, and magnetic field strength—have a major influence on lesion detection.

Magnetic Resonance Imaging (MRI) of Multiple Sclerosis

With the fat gone, the area holds more water and shows up on an MRI scan as either a bright white spot or a darkened area depending on the type of scan that is used.

To be very specific, MRI works in the following way:. Read Article. Momentum profiles Frederik Barkhof, MD, a researcher who won the John Dystel Prize for advancing our understanding and clinical use of brain imaging.

Read Profile. MRI is particularly useful in detecting central nervous system demyelination — that is, damage of the myelin sheath in the nervous system. This makes it a powerful tool in establishing the diagnosis of MS. MRI is particularly helpful in people who have had a single demyelinating attack that is suggestive of MS, also called clinically isolated syndrome CIS.

After an MS diagnosis, MRI scans help healthcare providers track the progress of the disease and help you make the best treatment decisions. For example, you and your provider may consider disease activity on MRI as well as symptoms and relapses in determining whether your current treatment is working or not.

In , MS experts from North America and Europe developed guidelines on the use of MRI to diagnose and monitor the MS disease course. Learn more about these guidelines through the Ask an MS Expert webinar below. Learn about the international recommendations for MRIs in a two-part episode of Ask an MS Expert with Dr.

Scott Newsome of Johns Hopkins. Part I explains what an MRI is and outlines the new protocols. Part II explores how MRIs can help you and your provider determine if your treatment is working. It also reviews special considerations for young people and pregnant people with MS. Watch the Webinar.

Various types of MRI scans are used in MS. Sometimes gadolinium, a contrast agent, is injected into the vein during an MRI to help detect areas of new inflammation.

Because gadolinium is a large molecule, it normally cannot pass through the blood-brain barrier, which prevents substances from passing from the bloodstream into the central nervous system. However, active inflammation can disrupt the blood-brain barrier.

Then gadolinium can enter and highlight the inflamed areas. Common MRI sequences used in MS include:. There are several forms of gadolinium-based contrast agents GBCAs.

Although GBCAs can be helpful, there are some risks to using them that you should know about:. Healthcare professionals may use a chemical contrast dye called gadolinium to improve the brightness of MRI scan images.

Learn more about what MS looks like on an MRI scan here. In MS, the immune system attacks and damages the protective myelin coating that surrounds the nerves. Healthcare professionals refer to this damage as lesions.

MRI scans can identify lesions that occur due to MS. MS lesions can show white matter inflammation, demyelination , and scarring, or sclerosis.

Scans can let healthcare professionals know when lesions are new and growing and potentially how damaging they are to the brain. The results of an MRI scan will look different depending on the type of MS that a person has. A person with clinically isolated syndrome CIS is experiencing the first episode of symptoms that occur due to inflammation and demyelination in the central nervous system.

The symptoms of CIS will last for at least 24 hours. CIS does not always progress to another form of MS. With relapsing-remitting MS RRMS , an MRI scan will show at least two separate areas of damage that have occurred at different points in time.

Some research suggests that RRMS tends to cause the highest number of new lesions among MS types. Learn more about RRMS here. People with primary progressive MS PPMS tend to have fewer brain lesions , and the lesions tend to contain fewer inflammatory cells.

They also tend to have more lesions in the spinal cord than people with other forms of MS. A study from found that people with four or more lesions with dark rims were 1. Lesions that appear rimmed on an MRI scan represent ongoing inflammation. Learn more about PPMS here. Secondary progressive MS SPMS is a form of MS that can occur in people who have had RRMS, and it features a general worsening of symptoms over time.

The worsening of symptoms is due to the nerve damage that has already occurred. Learn more about SPMS here. MRI scans do not use radiation.

The technician obtains the scan using a large, tube-shaped magnet. Various types of MRI scans can monitor MS activity in the brain. Healthcare professionals can carry out different types of scans during the same MRI session. T-1 scans can involve the use of gadolinium, which is a contrast dye, to look for new or growing lesions.

Permanently damaged areas of the brain appear as dark spots. These are also known as black holes or hypointense lesions. According to some researchers , chronic active lesions are very damaging to the brain.

These lesions require treatment as early as possible. A T-1 weighted scan without contrast dye can show hypointense lesions, which may indicate areas of permanent nerve damage. New MS lesions appear as bright spots on a T-2 scan.

These are also known as hyperintense lesions. Typical lesions that appear on a T-2 scan are oval in shape. Fluid-attenuated inversion recovery imaging reduces interference from the spinal fluid to help view the effects of MS.

Anomalies remain bright, while normal brain fluid looks dark. Spinal cord imaging can show that damage has occurred in different parts of the central nervous system at different points in time. There, imaging specialists can work in conjunction with neurologists outside the department.

When a primary care physician or a neurologist suspects that you have MS, they will follow a number of steps in order to confirm the diagnosis. That includes performing lab tests that include cerebrospinal fluid samples and blood tests.

You will also have your brain scanned. Is the white matter injury active or old? Our patients typically fall into two categories: those who worry that they may have MS, based on preliminary diagnosis by their physician, and those who already have MS and seek updates on their disease.

For patients who already have the diagnosis, a magnetic resonance imaging scan MRI can help doctors study whether a therapy is working. If a patient presents with new symptoms, Dr.

While general brain scans are often performed using computerized tomography CT , MRIs are used to scan for MS; in the images, doctors are looking for abnormal white matter. Minja says. They often introduce gadolinium, an injected contrast dye, which helps to detect active white matter injury.

Often people are given headphones to make this more tolerable. As the scanner is a very powerful magnet, all metallic objects must be left outside the scanning room.

It is advisable not to wear clothes with metal poppers, zips or metal buckles. Professor Coles talks about why magnetic resonance imaging MRI scans are used in the diagnosis of Multiple Sclerosis. The nucleus at the centre of a hydrogen atom spins like a top.

The strong magnetic field in an MRI machine more than 10, times stronger than gravity makes the atoms line up in the direction of the magnetic field. The machine then fires a pulse of radio waves that causes the atoms to spin in a different direction causing 'resonance'.

When the pulse is turned off, the atoms return to their natural alignment within the magnetic field and release energy. The machine picks up this signal and sends it to a computer, which converts it into an image. The chemical make up of the scars caused by MS means that they show up as white patches on MRI images, giving a very clear picture of the effects of MS on the brain and spinal cord.

By using a contrast enhancing agent called gadolinium, which is injected before the scan, damage to the blood brain barrier can also be identified, which indicates areas of active MS.

Two types of MRI scan are generally carried out when looking for MS lesions, inflammation and loss of neurons. The main type of scan used in the diagnostic process is known as a T2 image.

This is used to determine the total number of lesions or overall disease burden. T2 lesions appear as bright spots on the scan which indicate areas where the myelin sheath has been damaged or destroyed.

Changes in the brain due to the ageing process also appear as bright spots on a T2 scan, which is why it can sometimes be difficult to distinguish the lesions seen in MS from the normal changes seen in the brain as a person ages.

Although less useful for diagnosis than a T2 image, the other type of image that can be taken is a T1 image. Areas where nerve cells have been permanently lost or damaged appear as dark areas on this type of scan.

A contrast dye called gadolinium can be used during a T1 MRI to enhance the sensitivity of the scan.

Multiple Sclerosis: MRI Results

These data are needed for proper comparative analysis of examinations that are performed at different time points and in different imaging centres.

This section should start with a comprehensive, systematic description of all imaging findings related to the specific clinical situation, using standardized terminology. Examples of such findings include:. The report should always contain a conclusion to briefly communicate the radiological interpretation, particularly as related to the clinical problem.

Examples of pertinent data include identification of typical or atypical MS lesions, or MS-unrelated lesions and the differential diagnosis thereof; fulfilment of MRI diagnostic criteria for dissemination in space and time; and evidence of disease activity and progression. MRI requests should include pertinent clinical information and formulate unequivocal clinical questions All clinical MRI examinations require a written and, ideally, structured radiological report that provides a systematic, comprehensive description of all the imaging findings related to the specific clinical situation and questions , , The MAGNIMS study group has formulated these guidelines to better define and optimize the use of brain and spinal cord MRI in the diagnostic process for MS.

Our recommendations promote standardized strategies that apply to the planning, performance and interpretation of MRI for clinical use. We believe that these guidelines can be easily implemented and should serve to maximize the contribution of conventional MRI to the management of patients with MS.

The added value of non-conventional MRI techniques in the diagnostic process for individual patients with MS remains to be established and requires further research.

These efforts all have the final goal of providing an accurate, early diagnosis of MS. In the version of this article originally published online, the last bullet point and footnote from Box 2 were missing. This mistake has been corrected for the print and online versions. Filippi, M. et al.

Gallagher, H. L, MacManus, D. If you have symptoms of MS , your doctor may order an MRI scan of your brain and spinal cord. The images produced allow doctors to see lesions in your CNS.

Lesions show up as white or dark spots, depending on the type of damage and the type of scan. It uses a powerful magnetic field and radio waves to transmit information to a computer, which then translates the information into cross-sectional pictures.

Although the procedure is painless, the MRI machine makes a lot of noise, and you must lie very still for the images to be clear. The test takes about 45 minutes to an hour. This is because not all lesions in the CNS are due to MS, and not all people with MS have visible lesions.

MRI with contrast dye can indicate MS disease activity by showing a pattern consistent with inflammation of active demyelinating lesions.

These types of lesions are new or getting bigger due to demyelination damage to the myelin that covers certain nerves. The contrast images also show areas of permanent damage, which can appear as dark holes in the brain or spinal cord. Following an MS diagnosis , some doctors will repeat an MRI scan if troubling new symptoms appear or after the person begins a new treatment.

Analyzing the visible changes in the brain and spinal cord may help assess current treatment and future options.

Your doctor may also recommend additional MRI scans of the brain, the spine, or both at certain intervals to monitor disease activity and progression. The frequency with which you need repeat monitoring depends on the type of MS you have and on your treatment. MRI will show different things based on the type of MS involved.

Your doctor can make diagnostic and treatment decisions based on what your MRI scan shows. A single neurologic episode caused by inflammatory demyelination and lasting at least 24 hours is called clinically isolated syndrome CIS. If this is the case, your doctor may consider starting you on a disease-modifying MS treatment because this approach may delay or prevent a second attack.

However, such treatments have side effects. Your doctor will weigh the risks and benefits of treatment, considering your risk of developing MS, before recommending disease-modifying treatment after an episode of CIS.

Someone who has had symptoms but no MRI-detected lesions is considered at lower risk of developing MS than those who have lesions. People with all forms of MS can have lesions, but people with a common type of MS called relapsing-remitting MS generally have recurrent episodes of inflammatory demyelination.

During these episodes, active areas of inflammatory demyelination are sometimes visible on an MRI scan when contrast dye is used. In relapsing-remitting MS , distinct inflammatory attacks cause localized damage and accompanying symptoms.

Each distinct attack is called a relapse. Each relapse eventually subsides remits with periods of partial or complete recovery that are called remissions. Rather than intense bouts of inflammatory demyelination, progressive forms of MS involve a steady progression of damage.

The demyelinating lesions seen on an MRI scan may be less indicative of inflammation than those of relapsing-remitting MS. Secondary progressive MS is a stage that some people with relapsing-remitting MS will progress into.

This form of MS is classified into stages of disease activity and remission, along with new MRI activity. Your use of this information means that you agree to the Terms of Use.

Those most commonly used in clinical practice include:. Active and inactive lesions can be distinguished on MRIs using a technique called gadolinium enhancement.

Normally, a protective wall called the blood-brain barrier stops any of this contrast agent from entering the brain and spinal cord, so no contrast agent is visible on the MRI scan.

However, active inflammation in a lesion causes this barrier to become leaky, resulting in a bright spot at that lesion as the contrast agent leaks past the barrier. These areas of active inflammation can be referred to as enhancing lesions.

The terms T1 and T2 refer to the time between the magnetic pulses and when the image is taken. Active gadolinium-enhancing lesions usually are imaged specifically via a T1-weighted scan, while T2-weighted scans are generally used to image the overall lesion load, both old inactive and new active lesions.

A T1-weighted scan without gadolinium can reveal persistent lesions, which can show up as dark areas. The T2-weighted FLAIR is a technique used to improve the detection of lesions by suppressing signals or interference from the cerebrospinal fluid CSF — the liquid that surrounds the brain and spinal cord.

MRI scanners rely on powerful magnets. Generally, the more powerful the magnet, the better the resolution of the image produced by the MRI scan. The strength of MRI magnets is measured by a unit called Tesla T. Most MRI scanners used in clinics have magnets of 1.

An MRI is generally considered a very safe procedure. The scan itself is not painful. Some people may feel claustrophobic during MRI scans ; anti-anxiety medications can help if this is a problem. Because the MRI uses powerful magnets, it can affect metal that is in or on the body.

To ensure safety, it is important to remove any worn metal jewelry, eyeglasses, etc. before a scan. People with certain metal implants should not undergo an MRI scan — clinicians typically will perform a detailed screening procedure to identify whether an individual has any implants or other conditions that might raise safety issues during an MRI.

Gadolinium-based contrast agents, sometimes called GBCAs, can be injected into the body prior to some MRI scans in order to help detect areas of active inflammation.

These agents are generally considered safe. In rare cases — specifically in people with impaired kidney or liver function — GBCAs can increase the risk of nephrogenic systemic fibrosis NSF , a serious condition marked by fibrosis scarring throughout the body.

Recent research has shown that GBCAs can be retained in deposits in the brain and other body tissues; these deposits have not been linked to any overt health problems, but their clinical relevance is not completely understood.

Typically, multiple images are acquired. These images are interpreted by a radiologist, and the results are shared with the primary healthcare team and communicated to the patient.

This process commonly takes a week or two, though turnaround times vary from clinic to clinic. Contrast agents like gadolinium are typically used to detect areas of active multiple sclerosis MS driving inflammation on MRI scans.

However, contrast agents are not needed for scans that detect any MS lesions actively inflamed or not , so it is possible to diagnose MS without the use of these agents.

It is generally recommended that, when feasible, patients should undergo scans both with and without contrast. This will help to facilitate an MS diagnosis, or not, as quickly as possible. MRI scans of the cervical or lumbar spine — the neck and lower regions of the spinal cord, respectively — may be useful for detecting multiple sclerosis MS lesions in those regions.

To receive a formal diagnosis of MS, a person must show evidence of lesions in at least two of four parts of the central nervous system, which include three brain regions and the spine. As such, an MRI of the spine may be useful in the diagnostic workup, but a spinal MRI alone cannot be used to diagnose MS on its own.

MRI is the gold standard for detecting and monitoring the lesions that result from myelin loss in the nervous system and define multiple sclerosis MS. While an MRI is almost always a critical part of the diagnostic evaluation, MRIs alone are not enough to confirm the diagnosis — other tests are needed to confirm that MS-like inflammation is the cause of the damage, and to rule out other conditions that may mimic MS.

You will also have your brain scanned. Is the white matter injury active or old? Our patients typically fall into two categories: those who worry that they may have MS, based on preliminary diagnosis by their physician, and those who already have MS and seek updates on their disease.

For patients who already have the diagnosis, a magnetic resonance imaging scan MRI can help doctors study whether a therapy is working. If a patient presents with new symptoms, Dr. While general brain scans are often performed using computerized tomography CT , MRIs are used to scan for MS; in the images, doctors are looking for abnormal white matter.

Minja says. They often introduce gadolinium, an injected contrast dye, which helps to detect active white matter injury. Magnets in the MRIs used for MS screening have the strength of 3 Tesla—some of the strongest used clinically.

Other imaging is typically done at half that strength, or 1. Some doctors are now using a 7 Tesla magnet for research purposes, to help them explore hypotheses about MS. A standardized MRI protocol for brain and spinal cord is crucial for comparing across studies or between centers.

T2W MRI cannot distinguish between acute and chronic lesions. Gadolinium provides useful information about new lesion activity and is helpful in ruling out alternative diagnoses such as neoplasm, vascular malformations, and leptomeningeal disease.

A single gadolinium-enhanced MRI can potentially provide evidence for dissemination in space and time. Spinal cord imaging is equally valuable to rule out spinal stenosis or tumor, and for detecting asymptomatic lesions when brain imaging is nondiagnostic in patients suspected of having MS.

Precise criteria may be too suggestive that MS can be diagnosed by MRI and a negative MRI at the time of CIS does not rule out MS. MRI evidence plays a supportive role in what is ultimately a clinical diagnosis of MS, in the appropriate clinical situation, and always at the exclusion of alternative diagnoses.

Inflammation from a new MS brain lesion breaks down the blood-brain barrier, allowing the gadolinium to leak into the brain. Any gadolinium deposits that healthcare professionals find on an MRI scan suggest that there is disease activity in the brain.

The body almost completely clears gadolinium from the central nervous system after 48 hours. Healthcare professionals use MRI scans to confirm a suspected diagnosis of MS. The first MRI scan helps serve as a comparison scan, especially in evaluating CIS.

A person with MS may expect to have routine monitoring of their condition every 3—12 months. The frequency at which a person should undergo scans depends on the following:. MRI scans use strong magnetic fields and radio waves to create detailed images of the central nervous system in individuals with MS.

It is a safe and noninvasive test. Healthcare professionals typically use MRI scans to both diagnose MS and to help monitor how a person responds to treatment.
