1985;144(2):381-5. By putting each normal MTR volume through this transform, all normal data were converted into pseudo-MS data. These measures were all common measures, such as the mean, which measures the average value of the set of MTR values, and the SD, which characterizes the variability of the MTR values around the mean. One Hundred and Fifty Years Ago Charcot Reported Multiple Sclerosis as a New Neurological Disease. J Neurol. These areas will show up as bright on the MRI when contrast is used. The measures that were significantly different with respect to these two groups were discovered. Nusbaum A, Lu D, Tang C, Atlas S. Quantitative Diffusion Measurements in Focal Multiple Sclerosis Lesions: Correlations with Appearance on TI-Weighted MR Images. These results confirm some of the previous findings of van Buchem et al (13, 14); that is, that the MTR mean and peak significantly decrease in MS patients as compared with normal control patients. Apakah Sclerosis Sistemik (Scleroderma) 4. The increase in parameter rg1 verifies that the majority of this increase must be in the first N/4-ordered MTR values (typically from 0.0 to approximately 0.20). Brain scans are T2-weighted fluid-attenuated inversion-recovery and spinal scans are T2-weighted fast spin-echo. DTI abnormalities, which are already detectable in patients with clinically isolated syndrome (CIS), become more pronounced as disease duration and neurological impairment increase. Your use of this website constitutes acceptance of Haymarket Medias Privacy Policy and Terms & Conditions. Additionally, secondary progressive forms include stages during which the condition worsens on a more gradual basis, similar to primary progressive MS. Since five normal subjects had an average of 4.2 studies each, 21 MTR volumes were transformed in the creation of the five pseudo-MS subjects. This article has not yet been cited by articles in journals that are participating in Crossref Cited-by Linking. MRI findings. Some of these diagnoses are easy to rule out with a simple blood test (e.g. Multiple sclerosis. If you have what you think may be MS symptoms, talk to your doctor. Accurate diagnosis of multiple sclerosis (MS) hinges on correct interpretation of a patient's clinical history and radiologic studies. Normal data were passed through this transform, creating a set of pseudo-MS data. A single neurologic episode caused by inflammatory demyelination and lasting at least 24 hours is called clinically isolated syndrome (CIS). Reich lab, NIH/NINDS. We provide a unique illustration of these . MRI differential diagnosis of suspected multiple sclerosis. AJR Am J Roentgenol. 3. Incidental MRI Anomalies Suggestive of Multiple Sclerosis: The Radiologically Isolated Syndrome. Interestingly, the change in all four of these parameters can be explained by the loss of voxels with MTR values in the range (0.300.60) without regard for the gain of voxels with lower MTR values. The scan is a highly-sensitive, non-invasive way to view areas of damage in the central nervous system (CNS). 1985;145(5):957-64. Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. Check for errors and try again. Different people experience trigeminal neuralgia in different ways. Technologic advances of MR in recent years have dramatically improved our understanding of MS disease. In addition, all 17 of these measures changed in the same direction. RESULTS: Seventeen of the 30 measures were determined to be significantly different when comparing the sets of normal and MS data. Miller D, Grossman R, Reingold S, McFarland H. The Role of Magnetic Resonance Techniques in Understanding and Managing Multiple Sclerosis. Diffusion tensor imaging (DTI) is an effective means of quantifying parameters of demyelination and axonal loss. "The diagnosis would be made primarily based on symptoms and other lab findings, although the diagnosis is easier to confirm using MRI," says Dr. Mendi. 2009;72(9):800-5. Our website services, content, and products are for informational purposes only. Register now at no charge to access unlimited clinical news with personalized daily picks for you, full-length features, case studies, conference coverage, and more. While this work has been based on each subject's mean value of each of the 30 measures, a longitudinal study of each of these measures over time would be a promising area for future work. They may show some peripheral enhancement, often with an incomplete ring unlike gliomas or intraparenchymal abscesses, which typically have a closed-ring enhancement. We avoid using tertiary references. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Individual variations are an important factor, and it is for this reason that the normal and MS comparison is not identical to the normal and pseudo-MS comparison (Fig 6). The initial symptoms in particular such as numbness, tingling, and blurred vision, for example may be highly nonspecific. Radiology. The term "multiple sclerosis" refers to the many areas of scarring (sclerosis) that result from destruction of the tissues that wrap around nerves (myelin sheath) in the brain and spinal cord. This transform will be referred to as a normal-to-MS transform. We can now use a technique called FLAIR to make it easier to spot the lesions. MS causes demyelination, or the damage of myelin.. You may be considered at high risk of MS if youve had CIS and an MRI scan shows MS-like lesions. Multiple Sclerosis adalah autoimun kronik, sel-sel radang yang dimediasi T-sel yang mempengaruhi sistem . One potential solution to this problem is to use the mean MTR histograms of a set of normal subjects imaged on two different units (or the same scanner after an upgrade) to create a normal-to-normal transform analogous to the creation of the normal-to-MS transform that was developed in this study. Their presence indicates a risk of 82% in five years, while a normal brain MRI carries a predictive risk of between 6-24% at five years. The frequency with which you need repeat monitoring depends on the type of MS you have and on your treatment. 1 Because there is no single highly specific biomarker for MS, misdiagnosiswhen a patient without MS receives an incorrect diagnosis of MSis unfortunately common. This type of analysis may be more specific for evaluating treatment effects than other MR imaging measures, such as quantifying contrast-enhancing lesions and/or total white matter lesion load. To further understand this reduction, it is informative to examine the normalized quadrant counts, c1n, c2n, c3n, and c4n. Seizures. This is known as clinically isolated syndrome (CIS)and not all patients go on to develop multiple sclerosis. If you have symptoms of MS, your doctor may order an MRI scan of your brain and spinal cord. Enter the email address you signed up with and we'll email you a reset link. Initially, all elements were set to 0. While the MTR values used to derive the simple statistics, the range statistics, and the order statistics are basically unlimited in resolution, this is not true of the histogram parameters, which are derived using binned MTR values. Multiple sclerosis (MS) is the most common immune-mediated inflammatory demyelinating disease of the central nervous system. Genetic diseases such as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL), mitochondrial diseases, and leukodystrophies should also be considered. nationalmssociety.org/What-is-MS/Types-of-MS/Clinically-Isolated-Syndrome-(CIS), msfocus.org/Get-Educated/Common-Questions - What is Multiple Sclerosis, nationalmssociety.org/For-Professionals/Clinical-Care/Diagnosing-MS/Diagnosing-Criteria, clevelandclinicmeded.com/medicalpubs/diseasemanagement/neurology/multiple_sclerosis/, my.clevelandclinic.org/neurological_institute/mellen-center-multiple-sclerosis/patient-education/hic-frequently-asked-questions.aspx, nationalmssociety.org/about-multiple-sclerosis/what-we-know-about-ms/diagnosing-ms/magnetic-resonance-imaging-mri/index.aspx, nationalmssociety.org/What-is-MS/Types-of-MS/Relapsing-remitting-MS, nationalmssociety.org/What-is-MS/Types-of-MS/Secondary-progressive-MS. Whats the Best Climate for You If You Have Multiple Sclerosis? The normal-to-MS transform was created through the matching of the mean MTR histograms of the normal data (labeled N 15) and the MS data (labeled MS 18). EBV), or at least a catalyst, has long been suspected due to the geographic distribution and presence of clusters of cases;however, no agent has yet been firmly confirmed. This form of MS is classified into stages of disease activity and remission, along with new MRI activity. Features favoring progressive disease include: The aim of treatment is twofold: to curtail progression (disease-modifying agents) and symptomatic relief. The digital press . Please login or register first to view this content. Examples of common clinical features include 23,24: A number of patterns of longitudinal disease have been described 11,12: As is evident from this list, there is overlap, and in some cases, patients can drift from one pattern to another (e.g. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Illustration of the three data sets that were used in this study. See your doctor if you experience any of these, There is some promising research, but at this time, there doesn't appear to be an effective method of multiple sclerosis prevention. National Multiple Sclerosis Society website. It should be realized that the model described in Figure 4 is a function of the scanner hardware and software as well as the underlying physiological differences between the MS and the normal groups. Rule out all other possible diagnoses. Living with MS can be stressful, and stress can actually exacerbate MS symptoms. I. For magnetization transfer studies, spin-echo images were obtained with imaging parameters of 600/16/2 (TR/TE/excitations), with (Ms) and without (Mo) a saturation pulse (600 MHz below water frequency B1). Your doctor may also recommend additional MRI scans of the brain, the spine, or both at certain intervals to monitor disease activity and progression. Characteristically, and by definition, multiple sclerosis is disseminated in space (i.e. Join Community. . Vasculitic autoimmune diseases such as systemic lupus erythematosus(SLE) and Sjgrens syndrome can also result in white matter abnormalities on MRI. 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. A type of imaging test called an MRI scan is an important tool in diagnosing MS. (MRI stands for magnetic resonance imaging.). Cog Fog: How to Deal with This Frequent MS Symptom, Christina Applegate and MS: The Early Warning Signs She Says She Missed, 7 Remedies for Constipation with Multiple Sclerosis (MS), Understanding Symptoms of Multiple Sclerosis (MS), The Possibility of Multiple Sclerosis Prevention. relapsing-remitting to secondary progressive). A complete list of these P values along with their direction of change is presented in the Table. Sheldon J, Siddharthan R, Tobias J, Sheremata W, Soila K, Viamonte M. MR Imaging of Multiple Sclerosis: Comparison with Clinical and CT Examinations in 74 Patients. Neurology. Clinical Radiographic Paradox Clinical Radiographic Paradox occurs when on clinical examination there are symptoms that do not match the MRI images. Thus, while no significant increase is found in the number of voxels representing lower MTR values, a significant increase is found in the percentage of the brain made up of these voxels. This study assesses clinical and imaging long-term data, after early or delayed interferon-beta-1b treatment in patients with a first demyelinating event suggestive of multiple sclerosis (MS), 11 years after enrollment in the Betaferon/Betaseron in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) study (304747). For example, in transforming a normal brain to one representative of the MS data set, approximately 75% of all voxels with an MTR value of 0.5 are removed; 14.4% of them are relocated to lower MTR values in a distribution shown in B, while 85.6% of them are lost. To obtain more information on these changes, the parameters resulting from the ordered MTR values (O1O8) can be examined. In the context of a histogram, these array elements are called bins. Thus, even if one could assume that the matching of the mean histogram of the two groups would force the mean of all 30 of the examined parameters to be the same, it does not follow that the statistical analysis between the two groups can be predicted. MRI Imaging in Multiple Sclerosis Appointments 866.588.2264 Appointments & Locations Request an Appointment Mellen Center Approach: MRI in Multiple Sclerosis Magnetic resonance imaging (MRI) plays a crucial role in multiple sclerosis (MS) diagnosis, disease monitoring, prognostication, and research. Ge Y, Grossman R, Udupa J, Babb J, Nyl L, Kolson D. Brain Atrophy in Relapsing-Remitting Multiple Sclerosis: Fractional Volumetric Analysis of Gray Matter and White Matter. This data structure is basically a one-dimensional array in which each array element represents a specific MTR range. Transverse myelitis "Idiopathic" transverse myelitis usually exhibits a rather different clinical phenotype to the spinal cord relapse of MS. Also, the symptoms typically. Peripheral neuropathy. (2011) Intracranial venous pressure is normal in patients with multiple sclerosis. The diagnoses listed below can cause neurologic symptoms that are similar to those caused by multiple sclerosis (MS). The assessment of . In general, this normal-to-MS transform depicts a loss of voxels at high MTR values and a gain of voxels at low MTR values when going from a normal brain to an MS brain. No one test can absolutely detect multiple sclerosis (MS), but certain tests including magnetic resonance imaging (MRI) can be used to help confirm the diagnosis. Using a Wilcoxon rank sum test, the normal and MS data are not significantly different (P = .0592), whereas the normal and the pseudo-MS sets are significantly different (P = .0277). AJR Am J Roentgenol. Clinical presentation is both highly variable acutely, as a result of varying plaque location, as well as over time. Latest News Your top articles for Wednesday, Continuing Medical Education (CME/CE) Courses. 18. Brain. In considering the groups of MS and normal subjects from the four simple statistical parameters (S1S4), only the mean that describes the average MTR value has significantly decreased. Features that may be present include: MRI has revolutionised the diagnosis and surveillance of patients with MS. Not only can an MRI confirm the diagnosis (see McDonald diagnostic criteria for multiple sclerosis), but follow-up scans can assess response to treatment and help determine the disease pattern. Each distinct attack is called a relapse. 4. There is a strong, well recognized female predilection with a F:M ratio of approximately 2:1 19. 2005-2023 Healthline Media a Red Ventures Company. The range parameters c3 and c4 describe a decrease in the total number of voxels with MTR values in the range (0.300.60). Cog fog can make people with MS feel like its more difficult to. 2017;38(9):1672-80. Characteristically, and by definition, multiple sclerosis is disseminated in space (i.e. 2018 Revised Guidelines of the Consortium of MS Centers MRI Protocol for the Diagnosis and Follow-up of MS. 26. (2018). Stosic M, Ambrus J, Garg N et al. MR Imaging in Multiple Sclerosis: Review and Recommendations for Current Practice. Your doctor will explain the procedure to you in detail, but if you have questions, be sure to ask them. The test takes about 45 minutes to an hour. Richards T. Proton MR Spectroscopy in Multiple Sclerosis: Value in Establishing Diagnosis, Monitoring Progression, and Evaluating Therapy. Using the N members of each set, S, the measures S1 to S4 were found. 2000;21(6):1039-42. Contrast dye, a substance thats injected into your vein, can be used to make some types of lesions show up more clearly on an MRI scan. Of these 17 measures, nine were found that could be used to state differences between the normal subject group and the MS patient groups using an value of 0.001. Dr. Boster said that MRIs for diagnostic purposes are lesion-centric, focusing only on what can be seen by MRI imaging in the normal-appearing white matter of the brain. Inaccurate MRI interpretation is the most common cause of incorrect diagnoses in patients with MS, underscoring the critical importance of the physicians familiarity with MS mimics.2 Taking a thorough medical history focused on questioning the patient about prior neurological episodes that might have been overlooked or dismissed by the patient remains crucial in any assessment for MS, said Nicoline Schiess MD, MPH, an assistant professor of neurology at Johns Hopkins University Multiple Sclerosis Center. what is scattered subcortical hyperintensities involving both cerebral hemispheres which may relate demyelinating/ischemic change Believe radiologist or neurologist? Just as looking at MS lesions using different orientations gives you a better sense of the anatomy of the lesions, using multiple MRI sequences gives a more complete picture of the age and activity of the MS lesions. Initially, simple group statistics were applied to the collection of MTR values. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images. 3. It is important to consider the effects of modeling a transform with the same data that will eventually be processed with that transform. Meyer-Schwickerath R, et al. Once a person is diagnosed with MS, regular MRI scans help in tracking the disease's progression, which can aid in making treatment decisions such as whether to continue with a current therapy or. Each relapse eventually subsides (remits) with periods of partial or complete recovery that are called remissions. They are usually multiple. Sometimes MRI reports describe lesions as hyperintense, hypointense, or isointense. Studies were performed on a 1.5-T MR unit and consisted of axial oblique 3-mm interleaved sections (n = 42), with a field of view of 24 cm and a matrix of 256 192. Magnetic resonance imaging (MRI). Sarbu N, Shih R, Jones R, Horkayne-Szakaly I, Oleaga L, Smirniotopoulos J. There is no cure for either disease. Aided by a high-powered brain scanner and a 3D printer, NIH researchers peered inside the brains of hundreds of multiple sclerosis patients and found that dark rimmed spots representing ongoing, "smoldering" inflammation, called chronic active lesions, may be a hallmark of more aggressive and disabling forms of the disease. MRI Characteristics of Patients with Antiphospholipid Syndrome and Multiple Sclerosis. 2014;202(1):W34-42. They include: This article concerns itself primarily with classic (Charcot type) multiple sclerosis. Multiple sclerosis (MS)is a relatively common acquired chronic demyelinating disease involving the central nervous system, and is the second most common cause of neurological impairment in young adults, after trauma 19. A similar action is performed for voxels with MTR values at other values, although the percentage of loss differs, as shown in A. Using the Wilcoxon rank sum test, these measures were compared with those of the normal group to discover which of the measures were significantly different ( = 0.05). MRI is the most sensitive method for revealing asymptomatic dissemination of lesions in space and time. Double Inversion Recovery Brain Imaging at 3T: Diagnostic Value in the Detection of Multiple Sclerosis Lesions. Acta radiologica 49:570-579. Weinshenker B, Bass B, Rice G et al. Learn about types of neuralgia, including trigeminal neuralgia and postherpetic, Learn how to detect the early signs and symptoms of MS, like vision problems, fatigue, and weakness. Whenever clinical or MRI signs suggestive of PML are encountered, natalizumab should be immediately stopped. Radiology. These findings rule out many infections that can mimic acute MS. By multiplying the first set by 3, one can arrive at a set of pseudo-MS data containing the same mean as the MS data; that is, (3,6,6,3,3,6). In this report, the mean MTR histogram of the normal subject group was compared with the mean MTR histogram of the MS patient group (Fig 3) to derive a transform (Fig 4) representing the differences between the two groups. Doctors will also use a contrast agent called gadolinium with a T1-weighted scan to focus on newer, active lesions. There is no single test that is diagnostic of MS, including MRI. CT features are usually non-specific, and significant change may be seen on MRI with an essentially normal CT scan. No abnormal findings on neurological exam. For every MTR value examined, the bin representing that value is incremented by 1. Last medically reviewed on March 31, 2020. The descriptive ability of this transform was examined by performing the same analysis on the normal and pseudo-MS groups as was performed on the normal and MS groups. 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. People with either disorder may experience muscle stiffness and. The contrast MRI is used to look for areas of active inflammation. CURRENT Diagnosis & Treatment in Neurology. The images produced allow doctors to see lesions in your CNS. With regard to the comparison of normal and MS subjects, 17 of 30 measures were statistically significant using an value of 0.05 (Fig 6). McNamara C, Sugrue G, Murray B, MacMahon P. Current and Emerging Therapies in Multiple Sclerosis: Implications for the Radiologist, Part 1-Mechanisms, Efficacy, and Safety. Axonal injury is also a prominent pathologic feature, especially in the later stages. The mean value of each of these 30 measures was determined for each normal and MS subject. 1 Presented in part as a poster at the annual meeting of the International Society for Magnetic Resonance, Vancouver, April 1997. Want to view more content from Neurology Advisor? Dr Schiess added that ancillary testing, including blood work, CSF findings, optical coherence tomography (OCT), and evoked potentials can also facilitate diagnosis. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. Youve read {{metering-count}} of {{metering-total}} articles this month. 21. The number of voxels with other high MTR values (>0.3) also decrease, but to a lesser extent. Many of the lesions may not be causing obvious symptoms. In general, in going from a normal to an MS brain, the gain in voxels with low MTR values was less than 15% of the loss in voxels with high MTR values. lesions occur at different times). Initially, a mapfile was created for each subject by removing the skull and extradural tissues in the Mo volume from their first examination. On MRI it presents as a large intra-parenchymal lesion with usually less mass effect than would be expected for its size. Lvblad K, Anzalone N, Drfler A et al. 1. Trigeminal neuralgia, sometimes called tic douloureux, is a type of nerve (neuropathic) pain in the side of the face and can be a symptom of multiple sclerosis. The application of DTI in Multiple Sclerosis (MS) has yielded noteworthy results. A simple example can be illustrative as regards this technique: let the following list of numbers represent a mean parameter value from the set of normal data (1,2,2,1,1,2) and let the next list of numbers represent the mean value of this same parameter for the set of MS data (2,5,8,0,5,7). Dr Lange is the chief neurologist at HSS and a professor of neurology at Weill Medical College of Cornell University, and Dr Melisaratos is a board-certified radiologist at HSS who specializes in neuroradiology. Tan I, van Schijndel R, Pouwels P et al. An MRI scan can determine with a great degree of certainty if a person is having a stroke or a multiple sclerosis flare-up, as stroke looks different than a multiple sclerosis lesion. As for the exact effect of different bin sizes on the found histogram parameters, this has not yet been investigated. (2018). Importantly,neuromyelitis optica spectrum disorder (Devic disease) was considered a variant of multiple sclerosis, but is now recognized as a distinct entity, and is therefore also discussed separately. A number of clinical variants are recognised, each with specific imaging findings and clinical presentation. However, in many cases, the white matter lesions as isolated observations are nonspecific and could be due to MS or another cause, explained Drs Lange and Melisaratos. Clinical Course and Disability. Caracciolo J, Murtagh R, Rojiani A, Murtagh F. Pathognomonic MR Imaging Findings in Balo Concentric Sclerosis. Discover seven remedies for people with multiple sclerosis (MS) and constipation, such as creating a bathroom, An irritated or damaged nerve can cause pain known as neuralgia. 16. elizabeth193366. The means of the two sets are 1.5 and 4.5, respectively. Everything clear except for a spot in my brain stem which has been there since i was 12 so they dont think its ms related. Next, all normal MTR data were put through this transform to create pseudo-MS MTR data. 8. multiple lesions in different regions of the brain) and in time (i.e. Current 2017 McDonald diagnostic criteria for multiple sclerosis include clinical, imaging and laboratory findings (Thompson et al., 2018).MRI is of utmost importance in the diagnosis of MS. A and B, Nonnormalized MTR histograms (A) and normalized MTR histograms (B). 1.Introduction. MS and ALS common symptoms, like fatigue, difficulty walking, and slurred speech. The MS subjects (two men, seven women; mean age, 37 years; range, 2444 years; Kurtze Expanded Disability Status Scale: range, 18; disease duration: range, 19 years; and minimum contrast-enhancing lesion frequency, 0.5/month) had an average of 9.4 studies per subject. The Karolinska Imaging Dementia Study, Progression of Microstructural Damage in Spinocerebellar Ataxia Type 2: A Longitudinal DTI Study, Thanks to our 2022 Distinguished Reviewers, Copyright American Society of Neuroradiology. These include 20,21: Multiple sclerosis was first defined by Jean-Martin Charcot(1825-1893), French neurologist, in 1868 27. A CT scan is much quieter than an MRI. 2023 by the American Society of Neuroradiology | Print ISSN: 0195-6108 Online ISSN: 1936-959X. Radiographics. AJR Am J Roentgenol. The demyelinating lesions seen on an MRI scan may be less indicative of inflammation than those of relapsing-remitting MS. With primary progressive MS, the disease is progressive from the start and doesnt involve frequent distinct inflammatory attacks. So the best way to increase the odds that your MS progresses . Healthline Media does not provide medical advice, diagnosis, or treatment. The principles of MS diagnosis are based on showing dissemination of white matter lesions in space and time. The other three parameters (ie, SD, skew, and kurtosis) were not changed significantly. Multiple sclerosis (MS) is a relatively common acquired chronic demyelinating disease involving the central nervous system, and is the second most common cause of neurological impairment in young adults, after trauma 19. Owing to its ability to depict the pathologic features of multiple sclerosis (MS) in exquisite detail, conventional magnetic resonance (MR) imaging has become an established tool in the diagnosis of this disease and in monitoring its evolution. The mean values for all four quarters of the data (mn1, mn2, mn3, and mn4) illustrate that, in MS subjects, each of these means is significantly lower than which occurs in normal subjects. (n.d.). In order to confirm the diagnosis of MS, your healthcare provider must be able to rule out other possible diagnoses that could explain the symptoms you are experiencing.. Overall life expectancy is also reduced, by 7 to 14 years 19. 1998;121 ( Pt 1)(1):3-24. Headache. Maravilla K, Weinreb J, Suss R, Nunnally R. Magnetic Resonance Demonstration of Multiple Sclerosis Plaques in the Cervical Cord. Summary : MR offers by far the most sensitive technique for detecting multiple sclerosis (MS) lesions and has proved to be an important paraclinical tool for diagnosing MS and monitoring therapeutic trials. In this way, all data acquired from one scanner can be transformed to appear as if they were acquired on another scanner, or all data acquired before an upgrade can be transformed to appear as if they were acquired after the upgrade. MRI can reveal telltale areas of damage called lesions, or plaques, on the brain or spinal cord. We will refer to this set of values from a single Mo-Ms pair as S and the total number of MTR values composing this set as N. Also, each individual element in S will be referred to as sj where j goes from 1 to N. The choice of 0.6 as a cutoff was determined empirically from the observation that almost no voxels contain an MTR value greater than this value. 5.
