目的 :分析原发性胆囊癌的影像学表现。方法 :回顾分析 1991～ 1996年期间本院经超声、CT、MRI和血管造影检查并经手术病理证实的此症 49例。结果 :原发性胆囊癌分 :肿块型、厚壁型及腔内型三种类型 ,影像诊断正确率分别为 :10 0 %、90 .9%及5 5 .6 %。结论 :早期胆囊癌影像学检查无特征性改变。腔内病变以超声和 MRI显示较好 ;肝脏和周围的侵犯以 CT、MRI显示明确 ;血管周围、腹膜后转移性肿大淋巴结以 MRI更为敏感 ;血管造影能很好地显示肿瘤本身 ,对周围脏器的侵犯则有一定的诊断局限性
Objective: To analyze the imaging findings of primary gallbladder carcinoma. Methods : Retrospective analysis of 49 cases of this disease confirmed by surgery, pathology, ultrasound, CT, MRI and angiography during 1991-1996. Results : The primary gallbladder carcinoma was divided into three types: primary tumor type, thick-wall type, and intraluminal type. The diagnostic accuracy rates were: 100%, 90.9%, and 55.6%. Conclusion: There are no characteristic changes in early imaging of gallbladder carcinoma. Intraluminal lesions were better demonstrated by ultrasound and MRI; liver and surrounding insults were clearly demonstrated by CT and MRI; perivascular and retroperitoneal metastatic lymph nodes were more sensitive to MRI; angiography could well show the tumor itself. Peripheral organ violations have certain diagnostic limitations
