Paper Abstract

The stable xenon/CT method has been expanded to study in addition to the tissue flow the flow of the vessels in the brain. This method was then applied to a series of baboon experiments to measure the flow and diameters of vessels and their dependence on the partial pressure of carbon dioxide (PACO2). The method uses the value of the flow to distinguish vessels from tissues. The results from an experimental animal study show that (1) the location of the vessels with a diameter larger than 0.3 mm can be detected, (2) the vessel flow follows a Poiseuilles type law, (3) the average of the vessel flow is much higher near the skull at low PaCO2, whereas at high PaCO2 the average vessel flow is nearer the center.
