FIG 2. Serial changes in the reperfused brain. Initial diffusion-weighted image shows a hyperintense lesion in the striatum, with temporal reversal on the image taken at 24 hours. The lesion becomes a wider area of infarction on diffusion- (white arrow) and T2-weighted images. rCBV maps show hyperperfusion in the striatum, which were shown to normalize on later images (black arrow).
