چکیده
Estimating Total Cerebral Blood Flow From the Initial Slope of Hydrogen Washout Curves • An initial slope index of total cerebral blood flow, measured by the hydrogen clearance technique, shows a high correlation with flows calculated by bicompartmental analysis. In 247 flow measurements done on 41 rhesus monkeys, a linear regression analysis between these two methods of calculating flow shows a correlation coefficient of 0.928 with a standard error about y values of ± 7.63. The initial slope index is not only faster but does not require that a steady state be maintained for ten minutes. Additional

An initial slope index of total cerebral blood flow, measured by hydrogen clearance from torcular blood, shows high correlation with flows calculated by bicompartmental analysis. In 247 flow measurements done on 41 rhesus monkeys, a linear regression analysis between these two methods of calculating flow shows a correlation coefficient of 0. 9280 with a standard error about y values of +7. 63. ...
متن کاملNoninvasive method of estimating human newborn regional cerebral blood flow.
A noninvasive method of estimating regional cerebral blood flow (rCBF) in premature and full-term babies has been developed. Based on a modification of the xenon-133 inhalation rCBF technique, this method uses eight extracranial NaI scintillation detectors and an i.v. bolus injection of xenon-133 (approximately 0.5 mCi/kg). Arterial xenon concentration was estimated with an external chest detec...
متن کاملCerebral blood flow and neuropsychological asymmetries in unilateral stroke.
BACKGROUND AND PURPOSE This study sought to determine the degree of agreement between asymmetries of neuropsychological functioning and nine methods of quantifying asymmetries of regional cerebral blood flow. METHODS The regional cerebral blood flow methods combined three markers of cerebral blood flow asymmetry (percent hemispheric difference, maximum percent probe-pair asymmetry, and number...
متن کاملCerebral blood flow in rats during physiological and humoral stimuli.
The technique for estimating cerebral blood flow (CBF) in anesthetized rats by injecting 133Xe into the internal carotid artery represents a potentially useful and inexpensive model for screening cerebral vascular responses to pathophysiological and pharmacological stimuli. We have examined associated neuropathology, the validity and the reproducibility of the method, and made comparisons of in...
