【摘要】 目的　探讨用核素肝胆动态显像诊断胆道术后胆道是否狭窄的价值。方法　胆道术后患者13例(术后狭窄8例,闭锁1例,无狭窄或闭锁4例) ,正常人对照15例。患者行核素肝胆动态显像,经计算机拟合作出活性 时间曲线,分别计算肝脏、胆总管和十二指肠各段的高峰时间、1/4排泄时间和1/2排泄时间。结果　①术后狭窄者胆总管和十二指肠曲线呈缓慢排泄状,术后闭锁者胆总管曲线呈平抛状,术后无狭窄或闭锁者的各段曲线形状与正常曲线基本相似;②狭窄者胆总管段在所设定的采集时间内未见1/4和1/2排泄时间,闭锁者十二指肠始终未显影;③狭窄和正常对照组相互之间两两比较,其排泄的高峰、1/4和1/2时间有显著性差异。结论　核素肝胆动态显像活性 时间曲线分析对诊断胆道术后是否存在胆道狭窄具有一定临床价值更多还原

【Abstract】 Objective To investigate the value of radionuclide hepatobiliary dynamic imaging in diagnosing stricture after biliary surgery. Methods 13 cases of patients with biliary surgery and 15 cases for normal control received 99m Tc-EHIDA dynamic imaging. The peak time,1/4 and 1/2 excretory time of liver, gallbladder and duodenum were respectively calculated. Results The excretory curve of patients with stricture after biliary surgery declined slowly and that of patients with atresia after biliary surgery was flat. 1/4 and 1/2 excretory time of stricture patients can’t be calculated while duodenum image of atresia patient can’t be seen. Distinct difference exist between stricture patients and normal person. Conclusion Analysis of activity verse time curve of biliary dynamic imaging is valuable to determine stricture after biliary surgery.更多还原
