Cerebral blood volume in man. Computer analysis of a computerized brain scan
R. D. Penn, R. Walser and L. Ackerman
Cerebral blood volume in man can be measured by subtracting computerized
axial tomogram density measurements taken before from those taken after an
intravascular marker is infused into the blood. The average blood volume is
3.0 ml/100 ml of brain tissue, with a range of 2.4 to 4.25. This method can
be applied in studying cerebral pathologic conditions. Areas of cerebral
edema, surrounding a tumor, have a decreased blood volume.
