Summary
Blood flow and blood volume were measured simultaneously in the same cerebral region in anaesthetized cats with controlled respiration. The measurements were made with the same scintillation-detector, using the freely diffusible indicator 133 Xenon for flow determinations and the intra-vascular indicator RISA (131I) for volume recordings. A very high correlation was found between volume and flow changes (r = .96, p < 0.001). This finding indicates that variations of regional cerebral blood volume are accompanied by proportional blood flow changes.
