摘要
目的通过对正常肝脏CT灌注成像与肝脏储备功能对照研究,确定准确的正常肝脏CT灌注值。方法选择无任何肝脏疾病的志愿者20例,采用Philips16排螺旋CT机,选择肝门层面为中心,包括肝门静脉、腹主动脉和脾脏在内进行CT灌注扫描,通过设备附带软件分别计算肝脏的灌注值;利用吲哚氰绿实验进行肝脏储备功能检测。结果20例平均肝脏CT灌注值肝动脉灌注量(HAP)=0.18±0.08 ml/min.ml,门静脉灌注量(HPP)=0.98±0.33 ml/min.ml,总肝灌注量(TLP)=1.1±0.12 ml/min.ml,肝动脉灌注指数(HAI)=19.2%,门静脉灌注指数(PVI)=80.8%;平均15 min吲哚氰绿潴留率(ICGR15)=1.8%。结论肝脏CT灌注成像能反映肝脏的血流动力学变化,可作为影像学评估肝脏储备功能的重要指标。
Objective To assess the precise value of CT perfusion imaging in normal liver.Methods CT perfusion imaging and hepatic reserve function of normal liver were performed in 20 volunteers without any liver disease.Results The hepatic arterial perfusion(HAP) = 0.18±0.08 ml/min·ml,portal vein perfusion(HPP) = 0.98±0.33 ml/min·ml,total liver perfusion(TLP) = 1.1±0.12 ml/min·ml,HAI = 19.2%,PVI = 80.8%,and ICGR15 = 1.8%.Conclusion CT perfusion imaging can well reflect the hemodynamic changes in the liver,and can be regarded as an important imaging indexes to evaluate the hepatic reserve function.
