Quantitative Measurement of Regional Cerebral Blood Flow and Oxygen Metabolism in Man Using 15O and Positron Emission Tomography: Theory, Procedure, and Normal Values
A method is described for quantifying regional cerebral blood flow (rCBF), oxygen extraction (rOER), and oxygen utilization (rCMRO2) in man noninvasivey, using inhaled 15O-labeled CO2 and O2 andExpand

TLDR
We describe a new technique for the analysis of dynamic positron emission tomography (PET) studies in humans, where data consist of the time courses of label in tissue regions of interest and in arterial blood, following the administration of radiolabeled tracers. Expand
