【摘要】 目的　探讨原发性胆囊癌ＣＴ的表现特征、病期判断和临床应用价值。方法　对经手术病理证实的３７ 例原发性胆囊癌与ＣＴ扫描结果进行了回顾性对比分析。结果　原发性胆囊癌根据ＣＴ表现分为：腔内型、厚壁型、肿块型。胆囊癌的主要转移形式是直接侵犯肝脏和淋巴结转移。结论　（１）临床上中晚期胆囊癌具有特异的ＣＴ表现，对良恶性胆囊疾患鉴别有一定意义；（２）ＣＴ对胆囊癌壁外侵犯与转移的判定具有一定敏感度，且特异性较高，尤其肝脏直接侵犯和淋巴结转移，应做为胆囊癌术前常规检查以指导治疗；（３）ＣＴ对胆囊癌手术前评估具有一定价值。更多还原

【Abstract】 Objective To evaluate the CT features and clinical application in patients with primary gallbladder carcinoma (PGC). Method CT images obtained from 37 patients with pathologically proved PGC were retrospectively analyzed. Results In the 37 cases of PGC, CT images displayed 3 patterns: ① an intraluminal mass protruding into the gallbladder;②asymmetric thickening and/or irregularity of the gallbladder wall; ③a mass that filled or replaced the gallbladder. The most common spreading patterns of PGC were direct extension to the liver and nodal involvement. Conclusions ①The middle and advanced stage gallbladder carcinomas bear special CT imagies which can differentiate the malignant from benign gallbladder diseases; ② For detecting the spread of gallbladder carcinoma CT imaging has low to moderate sensitivity, however, it could be helpful in planning the treatment before operation because of its high specificity, especially for patients with nodal involvement and hepatic invasion; ③ CT findings bear a role in determining resectability of advanced stage gallbladder carcinoma.更多还原
