99mTc-HMPAO single-photon emission tomography in the standing position in cerebral infarction
Consecutive 99mTc-HMPAO studies were performed before and after standing, to the cerebral flow perfusion of the cerebral infarction and normal control. In normal subjects, standing stress decreased the blood flow of the superior frontal, the parietal and the inferior frontal lobes significantly. Standing stress did not decrease the blood flow of the superior frontal lobe and temporal lobe in lacunar infarct patients. The blood flow between standing and supine positions changed significantly around the cerebral infarct in a patient with middle cerebral artery occlusion.
