核多功能仪首次通过法测定门静脉肝动脉血流的价值及临床意义

THE VALLUE AND CLINICAL SIGNIFICANCE OF PORTAL VENOUS AND HEPATIC ARTERIAL BLOOD FLOW MEASURING WITH NUCLEAR MUTIPLE FUNCTION INSTRUMENT BY FIRST PASS METHOD

本研究以核多功能仪首次通过法为手段,以门静脉和肝动脉血流百分数、门静脉和肝动脉斜率为肝血流灌注指标,对25例正常人、125例各种慢性肝病患者作了测定。正常人结果与文献报道基本一致;各种肝病的结果与各自的病理变化相吻合;重复检测两次结果无差异。提示本测定方法稳定,结果可靠,具重复性,并有非创伤、简便、快速、价廉之优点;对了解肝病时肝脏的器质性变化及其程度有较大的参考价值,并有助于各种肝病的诊断和鉴别诊断。

In this paper, portal venous and hepatic arterialblood flow proportion (PVF%, HAF%) and theirslope (K_v, K_A) were measured in 25 nomal adult and125 partients of various chronic hepatic disease by usingthe first pass method of nuclear multiple functioniustrument. The results in normal people were corre-spond with the report of literatures completely. The re-sults in various hepatic discase were compatible withtheir pathological changes. There is no significant differ-ence in the repeated test. The data show that the meth-od was reliable. reproducible noninvasive. rapid andinexpexsive. It is useful to find organic changes ofhepatic disease and its severe degree and helpful tomake dignosis and differential dignosis in various chronichepatic diseases. It is good method to studied thechanges of hepatic hemodynamics.
