CT-based assessment of acute stroke: CT, CT angiography, and xenon-enhanced CT cerebral blood flow.
BACKGROUND AND PURPOSE Only a small percentage of acute-stroke patients receive thrombolytic therapy because of time constraints and the risks associated with thrombolytic therapy. We sought to determine whether xenon-enhanced CT (XeCT) cerebral blood flow (CBF) and/or CT angiography (CTA) in conjunction with CT can distinguish subgroups of acute ischemic stroke victims and thereby better predi...
متن کاملLocal Cerebral Blood Flow by Xenon Enhanced CT
Local Cerebral Blood Flow by Xenon Enhanced CT To the Editor: We take exception to the remarks of Gur et al in their recent Progress in Cerebrovascular Disease article (Stroke 13: 750-758, 1982), which may mislead your readership as to the magnitude of the errors associated with xenon CT measurements of rCBF. In discussing our error analysis of the single-scan "autoradiographic" approach to xen...
متن کاملComparison of xenon-enhanced CT with ultrafast CT for measurement of regional cerebral blood flow.
PURPOSE To compare an ultrafast CT method for estimating regional cerebral blood flow with a more commonly used xenon-enhanced CT method. METHODS Xenon CT and ultrafast CT were used to estimate regional cerebral blood flow (rCBF) in 12 healthy beagle dogs. Measurements were obtained for left and right hemisphere, cortical gray matter, basal ganglia, and deep white matter. The ability of each ...
متن کاملAccuracy of xenon CT measurement of cerebral blood flow.
In recent years, quantitative determination of cerebral blood flow (CBF) by xenon-enhanced CT has become an increasingly important research and clinical tool. Concurrently, the possibility that inhalation of stable xenon in the concentrations required for this procedure might itself alter CBF also has received increasing attention. Several studies [1-6] have examined this problem by using vario...
