A 58-year-old woman with left-sided weakness. A−D, NCCT (A) shows left periatrial microvascular ischemic changes (arrows) corresponding to perfusion abnormalities of CBF (B), CBV (C), and MTT (D) maps (arrows). Strategically located infarcts may be symptomatic though small and difficult to detect. No gross asymmetric perfusion is seen in the region of the right internal capsule. E, DWI performed on the same day shows a small acute infarct in the posterior limb of the right internal capsule.
