Regional cerebral blood flow estimated by 133-xenon inhalation.
A method is described for estimating the clearance rate and fractional blood flow of the fast (gray matter) compartment of the brain from the first ten minutes of 122 XE clearance curves, following a one-minute inhalation. Computer-simulated data were used to test the adequacy of the two-compartmental model employed, and to evaluate the stability of the parameters in the presence of random nois...
متن کاملDetermination of regional cerebral blood flow by inhalation of 133-Xenon.
A method for estimating regional cerebral blood flow is described in which tracer amounts of Xe are inhaled for 2 min and monitored extracranially over the next 45 to 60 min. A three-compartment model used to analyze the resulting clearance curves provided separate blood flows for "gray" and "white" matter, plus a decay constant for a slow third component, believed to arise from extracerebral t...

متن کاملXenon-133 inhalation method for regional cerebral blood flow measurements: normal values and test-retest results.
The purpose of this investigation is to determine the normal values for regional cerebral blood flow (rCBF) as determined by the xenon inhalation method of Obrist. Normal values for all rCBF parameters were measured in 15 healthy individuals. Our data are compared with the normal data obtained by other investigators. In addition, test-retest rCBF measurements were performed to determine the rep...
متن کاملRegional cerebral blood flow in acute stroke: preliminary experience with the 133 xenon inhalation method.
Regional Cerebral Blood Flow in Acute Stroke: Preliminary Experience With the Xenon Inhalation Method • The ""Xenon inhalation method of measuring regional cerebral blood flow was applied in serial studies comprising 100 measurements in 57 cases of acute hemiparesis and hemiplegia presumed due to arterial occlusion. Satisfactory data for analysis were obtained in over 95% of the cases studied. ...
