目的 :评价磁共振成像 (MRI)及磁共振胰胆管造影 (MRCP)在肝门胆管癌的分型和分期诊断中的作用。方法 :回顾性分析 2 3例肝门胆管癌的 MRI及 MRCP影像特点 ,并与手术及病理结果对照。 结果 :肿瘤按形态分型 :浸润型 11例、肿块型 12例 ;按侵犯肝门胆管范围 Bism uth分型 : 型 2例、 型 15例、 型 6例 ;肿瘤侵及血管 9例 ;无淋巴结、肝内或腹腔转移。结论 :MR对肝门胆管癌的大小、分型以及对胆道受累范围的估价是有效可靠的 ,对肿瘤侵犯血管范围的估价与病理结果接近 ,但尚有不足。
Objective: To evaluate the role of magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) in the diagnosis and staging of hilar cholangiocarcinoma. Methods: The characteristics of MRI and MRCP images of 23 cases of hilar cholangiocarcinoma were retrospectively analyzed. The results were compared with the surgical and pathological results. RESULTS: The tumors were classified according to the morphology: 11 cases infiltrated and 12 cases with tumor; Bism uth classification according to the range of hilar bile duct invasion: 2 cases, 15 cases, 6 cases; 9 cases of tumor invading blood vessels; no lymph nodes Intrahepatic or intraperitoneal metastases. Conclusion : MR is effective and reliable in the evaluation of the size and type of hilar cholangiocarcinoma and the range of involvement of biliary tract. The evaluation of the range of invasion of the tumor is close to the pathological result, but it is still insufficient.
