[摘 要 ] 目的 对比两种口服造影剂在多层螺旋CT小肠造影中的应用. 方法 44例临床患者（40～60岁）随机分为两组,分别使用常规法（碘伏醇水溶液）和改良法（甘露醇+碘伏醇水溶液）进行多层螺旋CT全腹扫描.按影像学解剖将小肠分为6段（1段为十二指肠,2段为空肠近端,3段为空肠远端,4、5、6段为回肠）,用双盲法对两组图像中小肠肠腔充盈度进行评价及统计学分析. 结果 改良法对2、3、4段小肠肠腔充盈度均优于常规法,差异有统计学意义（P＜0.05）；对1、5、6段小肠肠腔充盈度,两法差异无统计学意义（P均＞0.05）. 结论 改良法对空肠及回肠上端肠腔充盈效果优于常规法,口服造影剂改良法的研究对多层螺旋CT小肠造影检查有一定意义.

[关 键 词 ] 造影剂；小肠造影

[Abstract] Objective To pare two oral contrast agents in multi-slice spiral CT enterography of small intestines. Methods Fourty-four patients (40-60 years old) were randomly divided into two groups and underwent conventional or optimized methods for multi-slice spiral CT total abdominal plain scan. According to the anatomy imaging divided small intestine into 6 sections, with the double blind method on 2 groups of images in the intestinal lumen of filling degree evaluation and statistical analysis. Results Optimized method was superior to conventional method in the expansion degree of the 2, 3 and 4 segments of the small intestine (P＜0.05). There was no significant differences between two groups of conventional or optimized methods on the other segments of
