胆囊癌的CT与B超诊断价值

Diagnosis of gallbladder carcinoma with US and spiral CT

目的探讨和比较CT、B超对胆囊癌的诊断价值。方法回顾分析42例经手术病理证实的胆囊癌CT、B超影像和临床资料,就其CT和B超的影像表现、强化方式、周围组织结构的关系、有无转移等进行对比分析。结果42例胆囊癌中CT诊断胆囊癌31例(占74%),B超26例(占62%)。结论CT对胆囊癌的诊断优于B超,并可对肿瘤对周围结构侵犯评估及病变的治疗方案的制定有重要价值。超声因无损伤、可反复、不同体位的检查等优点可作为胆囊病变的筛查方法。

Purpose To evaluate the role of US and spiral CT in diagnosis of gallbladder carcinoma. Methods 42 patients with gallbladder carcinomas proved by operation and pathology were retrospectively analyzed. The two-phase enhanced spiral CT features and US manifestation of gallbladder carcinoma were reviewed. The enhancement pattern of the gallbladder wall were analyzed. Results In 42 before operation cases gallbladder carcinoma, 26 cases were diagnosed by US and 31cases by CT. The pathological resuls were as follow： 40 cases adencareinoma and 2 cases squamous carcinoma. Conclulion US can be considered the chief screening examination of gallbladder carcinoma. Spiral CT appears to be more valuable to estimate the extent of the disease and guide surgical processures.
