【摘要】 目的　探讨结肠腺瘤 ,结肠癌 ,结肠憩室 ,溃疡性结肠炎 ,结肠黑变病等病变的CT仿真结肠镜表现 ,初步评价其在结肠病灶诊断中的应用价值。方法　 37例病人 (包括 2 0例结肠腺瘤 ,6例结肠癌 ,4例憩室 ,5例溃疡性结肠炎 ,结肠黑变病及结肠淀粉样变各 1例 )行CT仿真结肠镜并和结肠镜检查结果作对照 ,男 2 6例 ,女 11例。结果　CT仿真结肠镜对结肠癌和结肠腺瘤、结肠憩室有较高的辨别率 ,成功地检出了 6例结肠癌、17例结肠腺瘤和 4例结肠憩室 ,而对于溃疡性结肠炎则辨别率较低 ,仅发现 5例中的 2例 ,对结肠黑变病和结肠淀粉样变则未检出。结论　CT仿真结肠镜能成功检出全部结肠癌 ,憩室及大部分腺瘤 ,部分溃疡性结肠炎。CT仿真结肠镜优点在于快速 ,无创伤性 ,病人耐受性好 ,容易接受。其缺点是不能直视下活检 ,对于小于 0 .5cm的病灶以及较为平坦的 ,表浅的病灶 ,显示率不高 ,无法显示黏膜色泽变化等。可以认为 ,CT仿真结肠镜虽无法完全替代结肠镜 ,但却是结肠镜一项良好的补充检查手段。它可能成为结肠病灶诊断的有效手段 ,可广泛应用于息肉切除术后的随访以及结肠癌的筛选更多还原

【Abstract】 Objective To investigate the value of virtual colonoscopy in the diagnosis of malignant and benign lesions in the colon. Methods CT colography was performed in 37 patients. Patients included 20 cases colon polyps, 6 cases colon cancer, 4 cases diverticulum, 5 cases ulcerative colitis and 2 cases other benign lesions. The colon lesions were evaluated with 2D and 3D images, depending on individual software. Results were compared with colonoscopy for each case. Results 17 cases colon polyps, 6 cases colon cancer, 4 cases diverticulum, 2 cases ulcerative colitis were detected by CTC. Conclusion CT virtual colography is a promising technique for the detection of colorectal lesions. This procedure is minimal invasive and fast, causes mild patient discomfort.更多还原
