肝门部胆管癌的影像学诊断价值（31例分析）

肝门部胆管癌主要靠影像学诊断、它提供手术切除性和手术方式选择的重要资料。我们复习了１９９１年９月至１９９６年９月的病历资料，将３１例经手术证实的肝门部胆管癌进行了分析和总结。以期了解Ｂ超、ＣＴ、ＰＴＣ、ＭＲＩ对肝门部胆管癌的诊断价值。结果：３１例术前经Ｂ超检查，诊断正确率为８６％，ＣＴ检查３０例，１７例正确。我们认为，Ｂ超操作简单，无创伤是首选的检查方式；ＣＴ不能显示肝门胆管癌肿块，但能显示肿块周

The role of radiologic imaging in the diagnosis of klatskin tumor:a study of 31 cases

The diagnosis of cholangiocacinoma in the hilar region (Klatskin tumor)depends largely on radiographic imaging. Imaging provides certain in formatins that is necesary for determining operability and the proper surgical procedure to be employed. 31 patients with klatskin tumors that had been surgied are analyed. We contrasted the preoperative diagnosis with the final diagnosis from september 1991 to september 1996. This artiele deals mainly with the role of US,CT,PTC,and MRI in the diagnosis of Klatskin tumor. Results:US was correct in 31 patients. CT was correct in 17 of 30 patients (57% ). concludes: US is much easier to perform and totally harmless. It is the first procedure. CT will delineate the dilatation of the biliary tracts peripheral to the mass. In the diagnosis of Klaskin tumor,US and CT are equally use but both are necessary
