CT胆管成像在疑诊胆道梗阻疾病中的应用

目的:探讨CT胆管成像(CTC)在疑诊胆道梗阻疾病中的应用价值。方法:对60例临床拟诊为胆道系统病变的病例行CT平扫及增强扫描,再用曲面重组、最低密度投影和多平面重组等方法重建出CT胆管成像(CTC)图像,结合两者作出诊断,与病理结果进行对照分析,计算CT+CTC对疑诊胆道梗阻病变的定位和定性诊断符合率。结果:胆管癌21例,胰腺癌18例,十二指肠乳头癌10例,胆管结石7例,胆总管囊肿3例,十二指肠乳头腺瘤1例。CT+CTC对疑诊胆道梗阻病变的定位和定性诊断符合率分别为100%和88.3%。结论:CT和CTC对疑诊胆道梗阻病变定位和定性诊断符合率高,具有良好的应用前景。

Value of CT cholangiography in patients suspected for biliary obstruction

Objective：To investigate the value of CT cholangiography in patients suspected with biliary obstruction.Methods：Sixty patients suspected for biliary obstruction were examined by unenhanced CT scanning and two-phase enhanced CT scanning.CTC was performed with CPR,MIP and MPR.Compared with the pathological results,the accuracy rates of CT and CTC in evaluating the sites and the causes were calculated.Results：21 cholangiocarcinomas,18 pancreatic cancers,10 duodenal papilla carcinomas,7 biliary tract stones,3 choledochal cysts and 1 duodenal papilla adenoma were found.Compared with the pathological results,the accuracy rates of location and characterization with CT and CTC were 100% and 88.3% respectively.Conclusion：The combination of CT and CTC attains high accuracy of diagnosis in the location and characterization of diseases in patients suspected for biliary obstruction,and has a good application prospect.
