Overview

Overview

Magnetic resonance imaging (MRI) is one of the most commonly used imaging modality in the workup of patients who are suspected to have cerebral vasculitis.Head MRI may be helpful in the diagnosis of microscopic polyangiitis. Findings on MRI suggestive of microscopic polyangiitis include cerebral hemorrhage and white matter lesions.
