FIG 1. Acutely hypoperfused lesion sizes, as measured with perfusion CT, for animals 1, 3, 4, and 5 at 30- and 150-minute time points after the start of endovascular occlusion. At each time point, the leftmost column corresponds to lesion size (in square millimeters) measured on the CBF map; middle column, lesion size measured on the CBV map; and rightmost column, lesion size measured on the MTT map. The dashed line represents outcome infarct size, as determined on the ex vivo T2-weighted MR image. Data for animal 5 were not available at 150 minutes after occlusion because of technical factors.
