本文介绍了首次通过法放射性核素肝动态显象肝动脉血流量（％Ｑａ）和门静脉血流量（％Ｑｐ）测定的原理和方法。对２２例正常人和６４例肝硬化病人初步测定结果说明：肝硬化组的％Ｑａ明显高于正常对照组，％Ｑｐ明显降低，各肝硬化组与正常对照组比较均有显著性差异。由此可见：％Ｑａ和％Ｑｐ的测定可用于肝硬化的早期诊断，是一种无创伤性定量测定肝硬化患者肝血流异常的有效方法。
This article presents the first principles and methods for the determination of hepatic arterial blood flow (% Qa) and portal vein blood flow (% Qp) by first passing radionuclide radionuclides. The preliminary results of 22 normal subjects and 64 patients with cirrhosis showed that the% Qa in cirrhosis group was significantly higher than that in normal control group, and the% Qp was significantly decreased. There was significant difference between each cirrhosis group and normal control group. Thus:% Qa and% Qp determination can be used for the early diagnosis of cirrhosis, is a noninvasive quantitative determination of hepatic blood flow abnormalities in patients with an effective method.
