CT与超声对胆囊癌诊断的对照分析

目的 探讨CT与超声诊断胆囊癌的优势及确诊率。方法 对经手术病理证实的、术前曾作过XCT及超声检查的35例胆囊癌进行回顾性总结分析。结果 35例胆囊癌中CT诊断正确率为65.7%，超声诊断正确率为77.1%。两者结合诊断正确率为82.9%。结论 CT对明确晚期胆囊癌对周围组织的侵犯程度有明显优势，超声对胆囊癌的早期发现优于CT，两者结合，可提高担囊癌的诊断正确率并准确分期，为临床提供可靠的信息。

Diagnosis of Cholecystic Carcinoma:A Comparative Study of CT and Ultrasound

Objective To investigate the superiority and the accurate diagnostic rate of CT and B-ultrasonography in diagnosing cholecystic carcinoma. Methods Thirty-five cases with pathologically-proved cholecystic carcinoma examined by CT and ultrasonography were analyzed retrospectively. Results In 35 cases of cholecystic carcinoma,the accurate diagnostic rates were:CT,65.7%;ultrasonography 77.1%;combining CT with ultrasonography 65.7%. Conclusions CT has evident superiority for diagnosing cholecystic carcinoma infiltrating to adjacent tissues.Ultrasonography is superior to CT in detecting the early stage cholecystic carcinoma.To combine CT with ultrasonography can raise the accurate diagnostic rate,define the stages of carcinoma.and offer reliable clinic informations.
