目的：探讨虚拟结肠镜诊断结肠息肉的准确性和可行性。方法以临床募集的20位患者为受试者，通过先行光学结肠镜检查记录息肉发现情况，然后立即进行薄层 CT 全腹部扫描获取数据，由有经验的消化科和影像科医生联合在虚拟结肠镜系统中查找息肉。结果虚拟结肠镜和光学结肠镜对于≥5 mm 的息肉有着相似的敏感度和特异性，但虚拟结肠镜较光学结肠镜缩短了检查时间，且没有侵入性。结论虚拟结肠镜作为一种新的结肠病灶筛查手段，对于≥5mm 的病灶，较光学结肠镜有更大的优势，易被患者接受，但对于较小的病灶难以检出。

Objective To compare the CT-based virtual colonoscopy and optical colonoscopy in a clinical setting.Methods Totally 20 patients were recruited and were subjected to optical colonoscopy and the polyp findings were recorded,and these patients were then immediately received thin-slice abdominal CT scanning and the data were acquired.Then the polyps in the virtual colonoscopy system were identified by both an experienced radiologist and a gastroenterologist.Results It was indicated that the virtual colonoscopy and optical colonoscopy had a similar sensitivity and specificity for polyps larger than 5 mm.Meanwhile,virtual colonoscopy needed a shorter examination time and the patients had a better patient experience than optical colonoscopy.Conclusion Virtual colonoscopy as a new screening method of colon lesions has a great advantage in detecting lesions larger than 5 cm,but not for a smaller one.
