Abstract： CT结肠造影(computed tomography colonography, CTC)为新近发展起来地结直肠病变检查手段, 是用多排螺旋CT技术将充气扩张的全结肠薄层扫描后的原始数据经相应的计算机软件处理后获得的一系列重建图像.因其简单、快速、安全、非侵入性等优点, 易于被患者接受.随着多层螺旋CT(multi-slice spiral computed tomography, MSCT)的应用和计算机软件的不断改进, CTC的图像质量和分析能力有了明显改善, CTC对1 cm以上息肉有很高的敏感性和特异性, 且在结直肠癌的准确诊断和正确的术前分期中显示了明显的优势.
