Overview
MRI
- Widespread, multifocal or extensive white matter lesions, more than 50% of the total white matter volume[1][2]. Bilateral abnormalities in the white to grey matter junction of the thalamus and basal ganglia have also been reported[3].
- Despite the absence of specific criteria, especially for children[2], follow up MRI scans at intervals no lesser than six months help establish or confirm the diagnosis of ADEM. The lesions should resolve or remain unchanged[4].
