MSCT胆管成像对高位胆管癌的诊断价值

目的：探讨MSCT胆管成像对高位胆管癌的诊断价值,为临床对高位胆管癌术前分型提供新的方法和依据。方法：利用16层螺旋CT对25例高位胆管癌患者行胆管成像检查,在工作站通过VR、MIP技术重组胆管树三维图像,对肿瘤类型作出评估,并与手术结果进行对照分析,评价MSCT胆管成像在高位胆管癌的应用价值。结果：25例患者经手术探查,在判断肿瘤分型上,诊断符合率为100%,术前评估结果与手术结果一致性极好。结论：MSCT胆管成像检查对胆管癌分型具有很高的准确性,在高位胆管癌术前评估以及制订手术治疗方案等方面具有重要的参考价值。

Clinical value of spiral CT cholangiography in preoperative evaluation of Klatskin tumor

Objective：To explore the clinical value of spiral-CT cholangiography in evaluation of Klatskin tumor.Methods：A prospective survey was performed to evaluate the resectability of 25 cases of Klatskin tumor by 16 detector-row spiral-CT cholangiogaphy.Before the operation,CT cholangiography was done,and then the reconstructions of hepatic bile tree were performed with the techniques of VR and MIP.The classification of the tumors was evaluated.The results were compared with operation exploration to evaluate the clinical value of spiral-CT chonlangiography in estimation of Klatskin tumor.Results：In the 25 patients who had been explored by operation,the coincidence rate was 100% in tumor classification which suggested a good coincidence between preoperative estimation and operation results.Conclusion：Preoperative spiral-CT cholangiography can give a rather precise diagnosis in classification of cholangiocarcinoma.It can provide important reference before operation for establishing the operation program.
