The computed tomographic colonoscopy (CTC) was performed in 212 patients on the multislice computed tomography Siemens Open in low-dose mode during the period from 2010 to 2013. CTC was tolerated well by 80% of patients. 20% of patients complained of mild discomfort during the study. The optical colonoscopy with biopsy was done in 53 (25%) of 212 patients after CPC. This is due to the fact that it was not detected the significant endoluminal structures in other observations or small polyps were found in elderly patients. In these cases the risk of colonoscopy was not justified. Sensitivity and specificity of CTC was 55 and 91% respectively for the detection of polyps with diameter less than 5 mm; for polyps 5-9 mm - 85 and 93%; for polyps with diameter greater than 10 mm - 100 and 92%.
2010年至2013年期间，对212例患者在西门子开放式多层计算机断层扫描上采用低剂量模式进行了计算机断层结肠成像（CTC）检查。80%的患者对CTC耐受性良好。20%的患者在检查过程中抱怨有轻度不适。在CTC检查后，212例患者中有53例（25%）接受了带活检的光学结肠镜检查。这是因为在其他检查中未发现明显的腔内结构，或在老年患者中发现了小息肉。在这些情况下，结肠镜检查的风险并不合理。对于直径小于5mm的息肉，CTC的敏感性和特异性分别为55%和91%；对于直径5 - 9mm的息肉，分别为85%和93%；对于直径大于10mm的息肉，分别为100%和92%。
