FIG 1. Representative PET images and histologic sections. Top, Sequential PET images of CBF obtained at control and at 2 and 24 hours after SSS occlusion. Arrowheads indicate regions of main decreased flow. Middle, rCBF thresholds on PET images at >30 mL/100 g/min (red). Bottom, Representative cross-sections of subacute hemorrhagic infarct (HE stain). Low-power view (original magnification x100) shows subacute, focally extensive hemorrhagic necrosis accompanied by eosinophilic hypoxic-ischemic neuronal changes in the high-power view (original magnification x400).
