| Outline of Final Research Achievements |
We evaluated atherosclerotic vessel wall lesions in intracranial arteries, including perforating arteries, among patients with acute stroke in the territory of the lenticulostriate arteries (LSA) using a high-resolution, three-dimensional (3D) T1-weighted vessel wall imaging (T1W VWI) at 7 Tesla magnetic resonance imaging (MRI) scanner. VWI showed atherosclerotic plaques in the bilateral M1 portions in all 15 patients. Although vessel wall thickening in the proximal portion of the LSA was identified in only 1 patient, high signal intensity in the distal portion of the LSA was observed in 7 patients. Use of the 3D-VWI at 7 Tesla MRI can provide direct visualization of subtle vessel wall lesions in the intracranial arteries, including perforating arteries, and can be helpful for understanding the mechanism for acute stroke.
