<jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Diagnosis of Moyamoya disease (MMD) is based on the characteristic angiographic findings. However, differentiating MMD from intracranial atherosclerotic disease (ICAD) is difficult. We compared vessel wall imaging findings on high-resolution magnetic resonance imaging between MMD and ICAD.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>High-resolution magnetic resonance imaging was performed on 32 patients with angiographically proven MMD and 16 patients with acute infarcts because of ICAD. Bilateral internal carotid arteries and steno-occlusive middle cerebral artery were analyzed for wall enhancement and remodeling.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p> Enhancement patterns and distribution were different. Most patients with MMD (90.6%) showed concentric enhancement on distal internal carotid arteries and middle cerebral arteries, whereas focal eccentric enhancement was observed on the symptomatic segment in ICAD. MMD was characterized by middle cerebral artery shrinkage; the remodeling index and wall area were lower in MMD than in ICAD (remodeling index, 0.19±0.11 versus 1.00±0.43; wall area, 0.32±0.22 versus 6.00±2.72; <jats:italic>P</jats:italic> <0.001). </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>MMD was characterized by concentric enhancement on bilateral distal internal carotid arteries and shrinkage of middle cerebral artery, regardless of symptoms.</jats:p> </jats:sec>
