摘　　要：目的:探讨64排螺旋计算机断层扫描结肠造影技术(computed tomography colonography,C T C)检查时双体位联合扫描对不同体位各段肠管扩张度的影响.方法:回顾性分析上海市第六人民医院36例患者64排螺旋计算机断层扫描(computed tomography,CT)结肠扫描图像,根据结肠的潴留液与固体残渣及各段肠管扩张情况进行评分,比较俯卧位和仰卧位各段结肠扩张度的差异.结果:除升结肠外,横结肠、降结肠及直肠-乙状结肠俯卧位与仰卧位肠管扩张度评分均存在显著性统计学差异(P<0.05).即降结肠、直肠-乙状结肠在俯卧位肠管扩张良好、液体及固体残留较少;相反,横结肠在仰卧位显示较好.结论:CTC检查中单纯的俯卧位或仰卧位均不能保证所有肠管的满意扩张,联合应用俯卧位和仰卧位扫描对于保证结肠的充分扩张是极为必要的.AIM：To explore the difference in colonic expansibility between supine and prone positions during 64-row multi-slice spiral computed tomography（CT） colonography.METHODS：Thirty-six patients received 64multi-slice spiral CT colonography in both supine and prone positions.The dilation of each colonic segment was scored based on colonic retention liquid,solid residues and intestinal canal expansion,and the difference in colonic expansibility between the prone and supine body postures was compared.RESULTS：Except the ascending colon,significant differences in colonic expansibility between prone and supine body postures were found in the transverse colon,descending colon and rectum-sigmoid colon（P〈 0.05）.In prone position,the dilation of the descending colon,rectum and sigmoid colon was better,while the dilation of the transverse colon in supine position was superior to that in prone position.CONCLUSION：When performing computed tomography colonography,neither prone nor supine body posture could guarantee the satisfying expansion of all colonic segments,and it is highly necessary to scan in both the supine and prone positions in order to ensure the sufficient dilation of the colon.
