"Identifying Active Multiple Sclerosis Lesions with MRI: The Significance of Dark Rims"

A study suggests that the T1-dark rim, a feature visible on standard MRI scans of people with multiple sclerosis (MS), could help identify paramagnetic rim lesions (PMLs), which are associated with disease activity and disability progression in MS. This finding could potentially enhance early detection and treatment adjustments for patients at higher risk of disease progression, as it offers an accessible marker for detecting these lesions without the need for advanced imaging techniques. However, further validation and studies are needed due to the small sample size and the relatively high false-positive rate of the T1-dark rim lesions.
