Branch atheromatous disease (BAD) refers to small, deep brain infarcts that are predominantly caused by the occlusion of perforating arteries, which may lead to single subcortical infarction (SSI). However, there is no in-vivo radiological evidence of plaques in the perforating arteries due to their small caliber. In this study, we used high-resolution black-blood imaging at 7T to display the vessel wall of the anterior choroidal artery (AChA), and analyzed atherosclerotic plaques of AChA in patients with isolated infarcts on the posterior limb of internal capsule. The delineation of AChA plaques provides direct imaging evidence for the etiological diagnosis of BAD.
