FIG 3. Images in patient 22, 6 d after SAH.
A, Hemorrhage is visible on this CT scan of the left sylvian fissure and perimesencephalic cisterns.
B, Spin-echo T1-weighted (501/16 [TR/TE[) MR image shows a high-signal-intensity change, due to T1 shortening, in the hemorrhage.
C, Diffusion-weighted image shows no abnormality.
D, Cerebral perfusion is reduced, as shown by increased time to peak in the left hemisphere on this map.
