Figure 2 :Acute right anterior cerebral artery stroke. The diffusion-weighted image shows patchy areas of restricted diffusion (infarct core). Perfusion-weighted imaging, specifi cally a time to peak map, demonstrates hypoperfusion in the ACA territory. A significant PWI-DWI mismatch is evident. Magnetic resonance angiography shows right A2 occlusion (arrow). In addition, the left internal carotid artery is not visualized due to a chronic occlusion
