Note:—CT indicates computed tomography; MRA, magnetic resonance angiography; DWI, diffusion-weighted MR imaging; ASPECTS, Alberta Stroke Program early CT score; mRS, modified Rankin Scale; ICA, internal carotid artery; MCA, middle cerebral artery; BG, basal ganglia.
* Site of arterial occlusion was not accurately determined due to poor image quality of MRA.
