原发性胆囊癌的CT诊断

Diagnosis of prhnary gallbladder carcinoma by CT

目的探讨CT对胆囊癌的诊断价值及准确性。方法回顾性分析经手术病理确诊的原发性胆囊癌26例患者的临床资料。结果26例患者均采用CT检查诊断进行确诊，原发性胆囊癌的CT表现：乳头腔内肿块型、局限或弥漫胆囊壁增厚、较大肿块充满或吞没胆囊型，结合病理可将胆囊癌的直接征象分为三种类型：浸润型、结节型、肿块型；胆囊癌的CT增强扫描表现：动脉期高密度，门静脉期等密度，其次为动脉期和门静脉期均为高密度，延迟期高于正常胆囊壁及肝脏，消退不明显，特别是胆囊癌结合部局部增厚的胆囊壁持续强化的特征。结论原发性胆囊癌表现复杂多样，CT检查不失为一种确立诊断的重要手段。

Objective To investigates the diagnostic value of CT of the gallbladder and accuracy. Methods Clinical data of 26 patients with pathologically confirmed gallbladder were retrospectively analyzed. Results 26 patients were diagnosed with CT. CT manifestations of primary gallbladder carcinoma： papillary intraluminal mass type, limited or diffuse gallbladder wall thickening, large cystic mass in full or swallowed type. Combined with the direct signs of pathology gallbladder cancer was divided into three types：infiltrative, nodular, tumor type;Enhance a performance of CT scan of gallbladder：artery of high density, such as density of the portal vein, followed by arterial and portal vein of both high-density, higher than normal latency of the gallbladder wall and liver, regression not significant, espe- cially gallbladder junction local thickening of the gallbladder wall continued enhanced features. Conclusion The performance of primary gallbladder was complex, and CT examination was a key means of establishing diagnosis.
