【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。更多还原

【Abstract】 Objective To compare 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 the small intestine(P>0.05).Conclusion Improvement on jejunal and upper ileal intestinal cavity filling effect is better than the routine method,modified method of oral contrast agent for multi-slice spiral CT angiography has certain significance of small intestine.更多还原
