Figure 1. Brain Magnetic Resonance Imaging of a Patient with Left Hippocampal Acute Infarction due to an Occlusion of the Left Posterior Cerebral Artery (PCA) in the P2 segment. Axial diffusion weighted imaging with b=1000 value (A) showing left hippocampal diffusion restriction (thick arrow) consistent with acute ischemic stroke in the PCA territory. Transversal maximum intensity projection time-of-flight image showing occlusion (thin arrow) of the left PCA in the P2 segment (B) with corresponding extensive perfusion deficit (multiple arrows) in the time to peak map (C).
