3 Patients were in the acutestage,〓FDG and 〓NH〓 PET showed brain stem infarction in 2 patients, while CT was normal. MRA of one of them showed right vertebral artery obstruction. One case showed focal infarction within the territory of the right middle cerebral artery 12 hours after stroke onset.〓NH〓 uptake was reduced in right frontoparietal lobe, putamen and part of thalamus, while hyperperfusion was observed in ipsilateral head of caudate nucleus and a portion of thalamus.
