Identification of the diffusion/perfusion weighted imaging (DWI/PWI) mismatch. Diffusion-weighted images (left) and perfusion-weighted images (middle) in an 80-year-old patient at 8 h after the onset of acute aphasia, left-sided sensorimotor hemiparesis, and hemianopsia. Note: the small hyperintense lesion in DWI compared with the large area of hypoperfusion in PWI. Magnetic resonance angiography (MRA) reveals proximal occlusion of the left middle cerebral artery (kindly provided by J. Fiebach, Department of Neurology, Charité Universitätsmedizin Berlin).
