16层螺旋CT与钡灌肠在结直肠癌诊断的对比研究
Comparative Study of Barium Enema and 16-Multislice Helical CT in Preoperative Diagnosis of Colorectal Carcinoma
-
摘要: 目的:探讨16层螺旋CT在中晚期结直肠癌诊断中的应用价值。材料与方法:对35例经病理证实的结直肠癌病人进行回顾性分析。通过MS-CTC检查进行术前Duke’s分期,并与手术病理分期对照分析。结果:BE检查32例,BE对结直肠病变的敏感度为97.5%,准确度为84.4%;MS-CTC检查35例,MS-CTC对结直肠病变的敏感度为100%,准确度为91.4%。MS-CTC对Duke’s分期诊断准确度率为85.7%。结论:BE是结直肠癌的常规影像学检查方法,MS-CTC检查能够提供多方面的诊断信息,对结直肠癌的诊断及术前分期都有重要价值。Abstract: Objective:To evaluate the diagnostic value of 16 multi-slice helical CT angiography(CTC)in colo-rectal carcinoma.Material and Methods:35 patients with histological proven colon or rectal carcinoma were included in this study.32 patients of them were examined by barium enema(EB),all of them were examined by MS-CTC in pre-operation.The preoperative staging of Duke’s were used based on the findings of MS-CTC.The results of MS-CTC were compared with those of surgical and pathological examination in all patients.Result: Among 32 patients were examined by EB,the diagnostic sensitivity of BE was 97.5%,and the accuracy was 84.4%.Among 35 patients were examined by MS-CTC,the diagnostic sensitivity of MS-CTC was 100%,and the accuracy was 91.4%.Thirty cases were correctly staged with Duke’s,the accuracy was 85.7%.Conclusion:BE can be considered as a primary approach for diagnosing colorectal carcinoma.MS-CTC examination can provide miscellaneous diagnostic information and can be of great value in diagnosing and preoperative staging of the colorectal carcinoma.
