Determination of cerebral blood flow with the EMI CT scanner

Abstract
Cerebral blood flow (CBF) determinations were made in 7 baboons (Papio) and 2 patients with the EMI CT [computer tomography] dedicated head scanner. The method for determining the CBF was tested and measurements were made during physiological stages elicited by changes in P[partial pressure]CO2 and depth of anesthesia. The method has a number of advantages particularly for assessing CBF responses to PCO2 changes.
