Until standardization of protocols and larger multicenter trials are performed, 1H-MRS remains relatively impractical for routine clinical use but promises ongoing valuable insights regarding molecular pathogenesis of MS disease processes and progression.

6. The presence of other factors, such as high brain lesion burden, brainstem or cerebellum lesions, spinal cord lesions, contrast-enhancing lesions, CSF oligoclonal bands, or abnormal visual evoked potentials, increase the likelihood of developing clinically definite MS[5], for which treatment with disease modifying therapy may be considered, with benefits and risks to be carefully weighed. Mainero C, Louapre C, Govindarajan ST, Gianni C, Scott Nielsen A, Cohen-Adad J, Sloane J, Kinkel RP. 1), with radially oriented, finger-like perivenular lesions adjacent to and parallel to the long axis of the lateral ventricles of the brain.

In multiple sclerosis, the segment of optic nerve involvement is usually short, unilateral and confined to the optic nerve itself, whereas in neuromyelitis optica (NMO) and MOG antibody-associated disease (MOGAD), involvement is typically bilateral, longitudinally extensive (>50% of the nerve) with extension to the intracranial compartment 6,7.

However, conventional MRI lesion measures lack specificity for the underlying MS pathology and only weakly correlate with clinical status.

Interestingly, although highly characteristic of the disease, T2 hyperintense lesion number and volumes show only modest and unreliable correlations with clinical status as measured by cognitive dysfunction and neurologic impairment on the expanded disability status scale (EDSS). We link primary sources including studies, scientific references, and statistics within each article and also list them in the resources section at the bottom of our articles. 2014;202(1):W34-42. 2008). White Matter Diseases with Radiologic-Pathologic Correlation. Multiple sclerosis (MS) is a chronic demyelinating condition affecting the central nervous system. Spinal cord atrophy can also be severe, and will be discussed below. The primary differences between an MRI and a CT scan are: A CT scan is much quicker and usually takes less than 10 minutes. 2014), and GM atrophy (Khalil et al.

Typical multiple sclerosis (MS) white matter and gray matter lesions in the brain as shown by cerebral 3T magnetic resonance imaging (MRI). Brain atrophy: An in-vivo measure of disease activity in multiple sclerosis. To validate this hypothesis, we analyzed the voxel-based association between R 2 and magnetic susceptibility in different DGM regions of 26 patients with multiple sclerosis and 33 age- and sex-matched normal controls. Ziemssen T, Derfuss T, DDe Stefano N, Giovannoni G, Palavra F, Tomic D, Vollmer T, Schippling S. 2015.

In healthy individuals, intravenously administered gadolinium contrast is sequestered mostly within the vascular structures of the brain, and shortens the T1 relaxation time to reveal arteries and veins as hyperintense. At Mellen Center, we prefer all MRIs to be performed on 3 Tesla strength machines, especially for spinal cord MRI as higher field strength MRI improves resolution and may increase yield in terms of lesion counts.

Recent studies have demonstrated that the presence of new or enlarging T2 lesions on follow up scans is sufficient as a surrogate for subclinical disease activity and progression [9], and did not perform worse than post-contrast T1 scans at detecting interval change [10]. 2015b); although this contrasts with a separate report using a different contrast protocol that identified leptomeningeal inflammation in <1% of patients (Eisele et al. 2015). Newer gadolinium agents are now used, which likely reduce the risk of toxicity; however, poor kidney function is a significant contraindication for use of these agents. Multiple sclerosis (MS) and fibromyalgia both involve the nervous system and cause chronic symptoms, such as pain and fatigue.

About 95% patients with clinically definitive MS have an abnormal MRI, but MRI is not a definitive investigation as up to 4% normal healthy individuals can have 2016). 2003.

The relation of AOC to outcome measures in MS still remains inconclusive.

Ultimately, however, it is unclear whether abnormal iron accumulation is a primary contributor to pathogenesis or a result of neurodegeneration (epiphenomenon) in MS. Proton MRS (1H-MRS) complements conventional MRI by allowing in vivo measurements of the relative concentration of certain biochemical metabolites.

Significant methodological variability, lack of large validated studies, and inherent patient pharmacodynamic heterogeneity limit the widespread clinical implementation of PET studies at present. Because brain atrophy has been shown to have such high clinical relevance, it is now regularly incorporated as a standard clinical outcome measure in large therapeutic trials (De Stefano et al. These studies suggest that tract-specific damage may explain variance in disability and offer the potential to bridge the clinicalMRI gap in predicting clinical outcome from imaging metrics.

2) (Masdeu et al. 7. Although gadolinium deposition has been reported in brain and other tissues of patients with normal renal function following administration of contrast, there are no known diseases or disorders associated with this finding [11]. CIS does not always progress to another form of MS.

We only use macrocyclic gadolinium-based contrast agents (as opposed to linear agents) due to its lower risk of associated gadolinium deposition in body tissues. 2007, Rojas et al. Brain MRI lesion load at 1.5T and 3T vs. clinical status in multiple sclerosis. Although there are no spinal cord equivalents of the BHs seen in the brain, quantitative measures of T1 relaxometry show diffuse changes that correlate with axonal and myelin pathology (Mottershead et al.

Contrast can rarely cause nephrogenic sclerosing fibrosis, but this is seen only in patients with severe renal disease and only in a small fraction of patients treated with contrast.

The reasons for significant variability in subacute phase T1 BH evolution are likely manifold, including methodological differences in imaging techniques (e.g., spin-echo and gradient-echo are not interchangeable in the characterization of BHs) (Dupuy et al.
