On the right, the non-contrast CT (NCCT) at the level of the basal ganglia. There were no signs of infarction or edema in the supratentorial and infratentorial structures. The corresponding relative cerebral blood flow (rCBF) and relative cerebral blood volume (rCBV) maps, at three different levels, are depicted on the left. The maps revealed a significant decrease in flow and volume in the left hemisphere, including the cerebellum, left midbrain, and pons, but flow and volume were preserved in the right hemisphere
