摘　　要：目的探讨16排螺旋CT结肠仿真结肠镜(CTVC)与电子结肠镜检查在结肠肿瘤诊断中的应用价值。方法 22例患者均先行电子结肠镜检查,再行螺旋CT容积扫描,将结肠仿真结肠镜成像与电子结肠镜检查结果进行比较。结果 22例患者中结肠癌(16例)以手术病理确诊为标准,电子结肠镜与仿真结肠镜对肿瘤的诊断符合率为100%,但CTVC检查同时还发现肠道外转移灶4例。电子结肠镜下检出结肠息肉(6例)11个病灶,CT仿真结肠镜检出(5例)8个病灶,诊断符合率83%,病灶检出率为73%。结论 CT结肠仿真结肠镜检查是一种无创、安全、可靠的技术,对肿瘤的诊断与电子结肠镜有同样高度敏感性,并能发现结肠以外病灶,但对结肠小息肉检查敏感性不高。Objective To investigate the value of CT virtual colonoscopy （CTVC） and Electronic colonoscopy （EC） in examining the colon tumors.Methods Twenty two cases were examed by EC and CTVC,images were contrasted.Results Sixty cases of colon carcinomas and 4 metastasis lesions were found by CT contrasted with operation.The diagnosis coincidence of colon tumor by EE and CTVC was 100%.11 （in 6 cases） were found by EC,and 8 （in 5 cases） lesions were found by CTVC.The diagnose accordance rate was 83%,the detection rate was 73%.Conclusion CTVC is an noninvasive,safe,reliable technique.Its sensitive to colon tumor is same as EE in finding epicolic lesions.But the sensitivity of small colonic polyps is not high.
