CT colonography is a new method for the detection of colorectal cancer and polyps.
The article is based upon a review of the literature in PubMed (1994-2005) for CT colonography, as well as the authors' own experience.
The seven largest publications show 55-94% sensitivity and 92-98% specificity for polyps > or = 10 mm. Compared to conventional CT examinations, the method has different requirements for patient preparation and technique. Our own experience so far is limited, but promising.
CT colonography seems to be a good alternative to the barium enema examination and a suitable supplement to incomplete colonoscopy. Hands-on training of radiologists is required before optimal results can be obtained.
CT结肠成像术是一种检测结直肠癌和息肉的新方法。
本文基于对PubMed（1994 - 2005年）中关于CT结肠成像术的文献综述以及作者自身经验。
七篇最大规模的出版物显示，对于直径大于或等于10毫米的息肉，其敏感度为55% - 94%，特异度为92% - 98%。与传统CT检查相比，该方法对患者准备和技术有不同要求。我们目前的经验有限，但前景良好。
CT结肠成像术似乎是钡剂灌肠检查的良好替代方法，也是不完全结肠镜检查的合适补充。在获得最佳结果之前，放射科医生需要进行实际操作培训。
