目的 :探讨螺旋CT胆道造影(SCTC)诊断胆道疾病的价值。方法 :胆道梗阻及胆囊病变28例。用30 %胆影葡胺40～60ml,加入5 %葡萄糖注射液150ml中 ,缓慢滴注延迟25分钟 ,行螺旋CT扫描并作三维成像。结果 :胆管显影率85 7 % ,24例显影患者显示阻塞部位及/或病变形态。结论 :SCTC能显示胆管狭窄部位、程度及原因 ,简单、可靠 ,有助于外科手术。并能观察肝分泌功能 ,估价胆汁流畅程度 ,是显示胆系阻塞的有效方法。
Objective: To investigate the value of spiral CT cholangiography (SCTC) in diagnosis of biliary tract diseases. Methods: Biliary obstruction and gallbladder disease in 28 cases. With 30% of the gallbladder amine 40 ~ 60ml, add 5% glucose injection 150ml, slow infusion 25 minutes delay, spiral CT scan and three-dimensional imaging. Results: The rate of development of the bile duct was 85.7%. The occlusion site and / or lesion morphology were shown in 24 cases of developing patients. Conclusion: SCTC can show the location, degree and reason of biliary stricture, which is simple, reliable and helpful to surgery. And can observe the secretion of liver function, evaluate the degree of bile flu, is an effective method to show the gallbladder obstruction.
