门脉循环γ照相与彩色多普勒对肝硬化的诊断意义

The Significance of Portal Circulation Scintigraphy and Colour Doppler Sonography in Diagnosis of Liver Cirrhosis

为评价门脉循环γ照相与彩色多普勒对肝硬化的诊断效能,18例肝硬化患者15例正常对照同时进行门脉循环γ照相和彩色多普勒扫描。结果表明,肝硬化组门脉分流指数(SI)明显高于对照组(P<0.01).诊断肝硬化灵敏度、特异性和准确性分别为83.3％、100.0％和90.9％。彩色多普勒扫描结果示,肝硬化组平均血液速度显著高于正常人组(P<0.05),两组门脉内径与血流量无显著差异(P>0.05),诊断肝硬化灵敏度、特异性准确性分别为66.6％、60.0％和63.6％。提示门脉循环γ照相对肝硬化化诊断意义,其诊断效能优于彩色多普勒。

To evaluate the diagnostic effecienty of portal circulation scintigraphy and colour doppler sonography in liver cirrhosis, 18 patients with liver cirrhosis and 15 normal subjects were determined by portal circulation scintigraphy and colour doppler sonography. The results of portal circulation scintigraphy showed that the portal shunt index (SI) of the liver cirrhosis group were significantly higher than that of nonmal subject group (P< 0.01). The diagnostic sensitivity, specificity and accuracy of SI were 83.3 % , 100.0 % and 90.9 % , respectively. The results of colour doppler sonography showed that the average blood velocity of liver cirrhosis group was markedly higher than that of normal subject group (P<0.05). There were not significantly different in internal portal diameter and blood flow between the two groups (P>0.05). The diagnostic sensitivity, specificity and accuracy of colour doppler sonography were 66.6% ,60.0% and 63.6% , respectively. The study indicates that portal circulation scintigraphy is significant in diagnosis of liver cirrhosis, and its diagnostic efficiency is better than that of colour doppler sonography.
