WebJ-STAGE Home WebThe ischemic penumbra is represented on MRI by the perfusion-diffusion (PWI-DWI) mismatch (Figures 3-11, 3-16, and 3-17). The PWI lesion corresponds to the area of hypoperfusion and the DWI lesion to the ischemic core. ♦. PWI-DWI mismatch is seen in approximately 70% of patients with proximal occlusion of the middle cerebral artery …

WebIn these cases, the penumbra volume was overestimated by MRI. DWI correlates with FMZ results and, with a few exceptions, yields a good estimate of acute tissue damage and final infarct volume. PWI measures seem to be less reliable; the TTP prolongation of >4 seconds assessed only 83% of the volume of hypoperfusion <20 mL/100 g per minute.
