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.
人体脑血容量可通过将血管内标记物注入血液后进行的计算机断层扫描密度测量值减去注入前的测量值来测定。平均血容量为每100毫升脑组织3.0毫升，范围在2.4至4.25之间。该方法可应用于研究脑部病理状况。肿瘤周围的脑水肿区域血容量减少。
