Figure 1: A 95-year-old woman presented with left hemiplegia. CT scan of the brain (A) shows a positive "dense MCA sign" (arrow) with the rest of the brain (B) showing relatively preserved gray-white matter differentiation. Time-resolved CTA (C) shows lack of flow in the right internal carotid artery (arrow) and the right middle cerebral artery (MCA) territory with delayed filling of the right distal internal carotid artery (ICA; arrow in D). Whole brain perfusion shows an almost complete right MCA territory-matched defect (arrows) on cerebral blood flow (CBF; E) and cerebral blood volume (CBV; F) maps. The whole extent of the right MCA territory infarct is better seen on the 3D reconstruction of CBF (G), CBV (H), mean transit time (I), and time to peak (J) maps
