Figure 2 Long- (rows A and D) and short-axis (rows B and E) views of inversion recovery gradient echo images acquired from 2 animals (top and bottom sets of images). The extracellular and intravascular gadolinium-chelates produced enhancement of acute infarctions (left blocks, arrows). In the long-axis view (rows A and D), the cores of acute infarctions show small patchy hypoenhanced regions, an indication of the presence of microvascular obstruction. In chronic infarctions (center blocks, arrows) the extracellular agent produced differential enhancement. Triphenyltetrazolium chloride staining (right slices C and F) confirmed the extent and location of infarction (arrows).
