摘　　要：本文通过对135例确定病因的阻塞性黄疸患者的CT分析,判断CT检查对胆管阻塞平面和阻塞原因的价值。扩张的肝外胆管在腹部扫描时所见为低密度环影,按其解剖分四部分:肝门段、胰上段、胰腺段及壶腹段。依据末环的形态、结石和肿块的出现,进行回顾性分析,CT确定梗阻水平的准确率为100％,梗阻原因为90.5％。以上说明CT检查可免去一些损伤性检查。The authors reviewed 135 cases of obstructive jaundice with confirmed causes to evaluate the CT value in determing the level of obstruction and the causes of jaundice. According to the number of low density circles which represented dilated extrahepatic bile duct. the extra hepatic bile duct was divided into 4 parts s. the perihilar segment, suprapancreatic segment , the mtrapancreatic segment and the ampullar segment. A retrospective study of the morphological appearance of the terminal circle of dilated bile duct and the demostration of stone or mass was done, The resaulfs shouwed that the CT accuracy rate in determining the level of obstraction was 100% , while in determining the cause of jaundice was 90. 5%. It appears that some invasive diagnostic methods used before can be avoided, by application of CTscan.
