Spinal cord MRI contrast enhancement using adaptive gamma correction for patient with multiple sclerosisMagnetic resonance imaging (MRI) is a clinically important tool for diagnosing several neurological diseases such as the multiple sclerosis (MS). Brain MRI has always facilitated the examination of the...

No specific tests can diagnose MS. You may need an MRI to take pictures of your brain. You may be given contrast liquid to help the pictures show up better. Tell a healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything...
"It is important to perform MRI with contrast to identify brain, spinal cord, and optic nerve inflammation," Professor Min said. "We can also identify oligoclonal bands and increased production of immunoglobulin G in the cerebrospinal fluid, which suggests a breakdown of the blood-brain barrier,...
Brain MRI without contrast agent is just as effective as the contrast-enhanced approach for monitoring disease progression in patients with multiple sclerosis (MS), according to a new study in the journal Radiology. The findings support the possibility t

Multiple sclerosis (MS) can be divided into four phenotypes based on clinical evolution. The pathophysiological boundaries of these phenotypes are unclear, limiting treatment stratification. Machine learning can identify groups with similar features using multidimensional data. Here, to classify MS subtypes...
Multiple sclerosis (MS) is a neurodegenerative disorder caused by the immune system mistakenly attacking the myelin sheath, a protective coating around nerve fibers. This results in inflammation, which further damages the myelin sheath, as well as the nerve cells themselves and the cells that ...
The T2 weighted image shows all multiple sclerosis lesions or plaques, whether active or inactive, and thus is a cumulative account of all multiple sclerosis activity, past and present. The T1 image without gadolinium contrast shows irreversible tissue loss as dark areas (“black holes”). The ...
