Background and purpose Along with intracranial atherosclerotic disease ( ICAD ), moyamoya MMD ) is the most common cause of middle cerebral artery MCA occlusion in Asians. Although they have differing vascular wall pathologies, conventional angiographic evaluation methods cannot easily differentiate from certain situations, such as young patients risk factors. High resolution magnetic resonance imaging HR ‐ MRI findings for diseased segments s symptomatic were compared to further elucidate differences arterial changes. Methods Angiographically confirmed patients, 12 20 , who suffered a stroke due recruited underwent . The size outer diameter other stenotic vessel characteristics revealed by including enhancement, eccentricity lesion patterns, analyzed two independent reviewers blind fashion. Results younger than (32.92 ± 11.08 years vs. 51.85 11.97 years; mean SD displayed smaller portion (1.61 0.43 mm 3.03 0.53 P < 0.0001). Eccentric lesions (three 19 0.0001) focal enhancements areas (two seven 13 17 = 0.061) less cases. Conclusions Our show that associated smaller, concentric occlusive which are rarely enhanced consistent results previous pathological reports. may therefore utility differentiating
