FIG 3. Pre- and postocclusion maps for animals 3 and 5. The first row and third row from the top present the CBV, MTT, and CBF maps from the control preocclusion study in animals 3 and 5, respectively. The second row and fourth row from the top present the maps obtained 30 minutes after the onset of MCA occlusion. In animal 3, right MCA territorial hypoperfusion is present, with involvement of the putamen and subtle involvement of the anterolateral thalamus. In animal 5, left MCA territorial hypoperfusion is clearly visible after occlusion, but the basal ganglia are spared. Note that each image is individually windowed to facilitate visualization of the lesions.
