MRI IN ACUTE DISSEMINATED ENCEPHALOMYELITIS

A retrospective analysis of CT and MRI studies in 12 patients with a c linical diagnosis of acute disseminated encephalomyelitis (ADEM) was p erformed. MRI was the definitive modality for the assessment of the le sions of ADEM: all patients had abnormalities consistent with the clin ical diagnosis. Ten had abnormalities in the brain, three spinal cord lesions, and three showed evidence of optic neuritis. CT was normal in 6 of the 7 patients in which it was performed.
