局部脑血流(Regional Cerebral Blood Flow,简写为rCBF)测定法是近年来迅速发展起来的检查项目.通过对rCBF的测定,可以确定脑各个部位的有效血容量,判断脑局部血液循环障碍的部位,并为研究影响脑血液循环的药物提供观察指标、进行疗效评定.因此,rCBF测定在基础医学研究与临床医疗工作中占有极重要的地位一、rCBF测定法的发展和原理rCBF测定法是在脑平均血流量测定法的基础上发展起来的.早在1811年,意大利医生Ravina就用犬颅骨开窗的方法,直接观察脑表面血管的搏动情况,推断脑血流量
Regional cerebral blood flow (Regional Cerebral Blood Flow, rCBF) assay is a rapidly developing test in recent years by measuring the rCBF, can determine the effective blood volume in all parts of the brain to determine the site of cerebral blood circulation disorders , And for the study of the impact of cerebral blood circulation drugs to provide indicators of observation, the curative effect evaluation. Therefore, rCBF determination in the basic medical research and clinical medical work occupies a very important position. RCBF assay development and principle of rCBF assay is The average brain blood flow measurement method developed on the basis.As early as 1811, the Italian doctor Ravina on the dog’s skull window method, direct observation of the surface of the brain blood vessels pulsation, infer the cerebral blood flow
