作者为56例胆系癌的病人和75例没有胆系病变体征的病人做了CT扫描。49例获得手术病理结果,1例有尸检结果,5例有经皮针吸结果,为了对肿瘤进行分类,作者把侵犯左右肝管末端及肝总管近端2cm的肿瘤定为近端肿瘤。把侵犯肝总管其余部分的肝外肿瘤划分为末端癌,这些导管都被侵犯的肿瘤划分为弥漫癌,侵犯胆囊或胆囊管的肿瘤划为
The authors performed CT scans for 56 patients with biliary carcinoma and 75 patients without signs of biliary lesions.

The extrahepatic tumors that invade the rest of the common hepatic duct were classified as terminal cancers. The tumors that were invaded by these catheters were divided into diffuse cancers. The tumors that invaded the gallbladder or cystic duct were designated as
