Regional blood flow in the normal cerebral hemisphere.
Measurement of the rate of clearance of 133Xenon from the brain after injection of this radioisotope into the internal carotid artery has become an accepted method for estimating cerebral blood flow (H0edt-Rasmussen, 1965, 1967; Ingvar, Cronqvist, Ekberg, Risberg, and H0edt-Rasmussen, 1965). Resolution of the clearance curves into two components, fast and slow, may be carried out (H0edtRasmusse...
متن کاملThe effect of cerebral infarction on the regional cerebral blood flow of the contralateral hemisphere.
Regional cerebral blood flow (rCBF) measurements were performed over the contralateral hemisphere by the 133Xe intracarotid injection method in 20 patients with acute cerebral infarction in the territory of the internal carotid artery. The rCBF was found to be reduced, sometimes remarkably, in all of the patients. The mean reduction was 30 percent to 36 percent from the lowest normal value for ...
متن کاملRegional cerebral blood flow in normal pressure hydrocephalus.
Regional cerebral blood flow (rcbf) was studied preoperatively and at 2 and 6 months postoperatively in 22 normal pressure hydrocephalus patients using xenon-133 inhalation and single photon emission computed tomography. Sixteen of the 22 patients improved (improved group) and six did not (unimproved group). The following comparisons were made: (1) preoperative rcbf in the improved group, to 14...

15 صفحه اولRegional cerebral blood flow in Alzheimer's disease.
Neural networks have been successfully applied to brain perfusion images to classify patients with Alzheimer's disease from normal or other patient populations. Given the recognition that Alzheimer's disease constitutes a heterogeneous disorder, the identification of subgroups sharing common functional brain deficits would constitute a further improvement in the utility of such methods. Therefo...
