摘要
目的评估低剂量C T结肠成像对腹部结肠外病变的诊断价值及其临床意义。方法回顾性分析158例低剂量C T结肠成像患者的影像资料，记录所有腹部的肠外病变，根据年龄将所有患者分为老年组以及非老年组；并根据病变的临床重要性将腹部所有肠外病变分为E1～E4组，分别比较老年组与非老年组之间发病率的差异。结果 E2～E4级病变总体发病率老年组高于非老年组，二者比较差异有统计学意义（P＜0．05）。结论低剂量CT结肠成像对腹部结肠外病变具有较高的诊断价值，且随着年龄的增长，有重要临床意义的肠外病变发病率随之增高，尤其是对于60岁以上的老年人。
Objective To evaluate the value of low-dose computed tomographic colonography （CTC） performed with 64-slice CT in the diagnosis of incidental extracolonic lesions and its clinical significance .Methods The image data in 158 CTC examinations with two positions were retrospectively analyzed .All abdominal extracolonic lesions were recorded .According to the age ,the pa-tients were divided into two groups ：elderly and non-elderly groups .The extracolonic lesions were divided into 4 groups（E1- E4） according to the clinical importance .The incidence rates in two groups were calculated respectively .Results The incidence rate of the E2-E4 level extracolonic lesions in the elderly group was higher than that in the non -elderly group ,the difference between them had statistical signficance （P〈 0 .05） .Conclusion Low-dose CTC has the high diagnostic value in finding extracolonic le-sions ,and the incidence rate of extracolonic lesions with important clinical significance is increased with the age increase ,especially for the elder patients over the age of 60 years .
