目的 探讨胆囊癌的CT表现及其诊断价值。方法 回顾分析了18例经手术病理证实为胆囊癌的CT影像诊断结果,讨论了CT扫描的分型、诊断价值及鉴别诊断问题。结果 CT对胆囊癌的诊断正确率为85％。根据胆囊癌的CT影像分为:壁厚型5例,腔内型4例,肿块型9例,伴有肝转移7例,胆道梗阻11例,总胆管转移6例,区域性淋巴结肿大为8例,伴胆结石的11例。结论 CT有较高的定位、定性正确诊断率,在显示肿瘤涉及范围优于B超。胆囊窝薄层及变换体位扫描有助于鉴别诊断。
Objective To investigate the CT appearance and diagnostic value of gallbladder carcinoma. Methods The diagnostic results of 18 cases of gallbladder carcinoma confirmed by pathology were retrospectively analyzed. The classification, diagnostic value and differential diagnosis of CT scan were discussed. Results The diagnostic accuracy of CT for gallbladder cancer was 85%. According to the CT image of gallbladder carcinoma, it was divided into 5 cases: wall thickness, 4 intracavity, 9 masses, 7 liver metastases, 11 biliary obstruction, 6 biliary metastases, and regional lymphadenopathy. 8 cases, 11 cases with gallstones. Conclusion CT has higher localization accuracy and correct diagnosis rate. It is superior to B ultrasound in displaying tumors. Gallbladder fossa lamina and shift position scans are helpful in differential diagnosis.
