摘要 目的 通过时相法心 /肝比值的测定 ,对肝硬化导致的肝门脉高压、门静脉分流以及肝脾功能进行综合判断 ;方法 放射性心肌灌注显像剂99mTc MIBI经直肠给药 ,通过门脉分流回流入体循环 ,使不应显像的心肌显像 ;通过计算心 /肝 (H/L)比值 ,对肝硬化程度进行判断。结果 正常组与肝炎、肝硬化组时相分时相心 /肝比值有显著性差异 (t=2 2 14,P <0 0 5) ;肝硬化组早期与肝炎组H/L比值无意义外 ,其余各组分时相均有显著性差异 (t=3 0 0 3,P <0 0 0 1)。结论 时相法心 /肝比值对肝炎、肝硬化所造成的肝功能减低、门静脉分流和门静脉回流的诊断有显著的意义 ,是一项比较灵敏而特异的指标。 Objective To estimate synthetical the high pressure of the diffluence of portal vein of liver and the function of liver and spleen by the measurations of apiece time appearance ratio of heart and liver (H/L).[WT5”HZ]Methods [WT5”BZ]Myocardiac perfusion raster display medicine of radioactivity ( 99 m Tc MIBI)is presented by rectum,and it circumfluents cycle of body by the diffluence of portal vein to make the myocardiac raster display.We estimate the degree of hepatocirrhosis by calculating the ratio of heart and liver.[WT5”HZ]Results [WT5”BZ]There is a marked difference between the ratios of H/L of the normality group and of hepatitis,hepatocirrhosis group ( t=2.214,P <0.05).Except for hepatitis group and the forepart of hepatocirrhosis group,the apiece time appearances of others groups are marked differences ( t= 3.003 ,P <0.001) [WT5”HZ]Conclusion [WT5”BZ]The ratios of apiece time appearances are obviously significance to estimate the letdown of function of liver,the diffluence and regurgitance of portal vein.
