Overview
On MRI, multiple sclerosis is characterized by cerebral plaques disseminating in space and time which are characteristic of demyelinating areas. These lesions are commonly void, and located in periventricular white matter, cerebellum, and the brain stem. These lesions are hyperintense on T2 sections of a MRI.
MRI
MRI may be helpful in the diagnosis of multiple sclerosis. Findings on MRI diagnostic of multiple sclerosis include:
- Disseminating lesions in space and time.
- cerebral plaques which are demyelinating areas.[1] These lesions are commonly ovoid, and located in periventricular white matter, cerebellum and brain stem.[2] These lesions are hyperintense on T2 sections of MRI. There are also gray matter lesions, presents as hypointensity in T2-weighted and are correlated with patients physical disability and brain atrophy.[3][4]
- Spinal cords lesions are common in MS disease and are often symptomatic. These lesions are focal or diffuse, small land located mostly in the cervical spinal cord. spinal cord findings can be very helpful for diagnosing MS rather than brain MRI only.[5][6][7]
- On T1-weighted MRI, MS lesions are isointens to white matter, but sometimes we see these lesions as a hypointens lesions called “black holes” mostly seen in supratentorial region . These black holes can disappear after several months due to remyelination but persistent black hole lesion can be a marker of active disease and demyelination injury.[8][9][10]
- We can see brain atrophy in MS patient especially in the thalamus areas. some studies show that thalamus atrophy can be an indicator of disease progression.[11][12]
NOTE: To differentiate acute and chronic lesion from each other, we most know that acute lesions tends to be larger in size with poor defined border, but chronic lesion are smaller due to reduction of inflammation and edema and have sharp borders in imaging.[13]
