两种口服对比剂在多层螺旋CT小肠造影中的应用对比

摘要

目的：研究多层螺旋CT小肠造影(MSCTE)中口服对比剂的选择应用。方法：回顾性分析70例进行MSCTE检查患者口服对比剂应用情况,50例检查前口服中性对比剂等渗2.5%甘露醇溶液,20例检查前口服阳性对比剂碘海醇的稀释液。结果：两组患者十二指肠、空肠、回肠扩张程度比较：t值分别为7.7807、6.6994和7.9721(P<0.05),差异有统计学意义,中性对比剂组优于阳性对比剂组；两组患者十二指肠和回盲部显示良好率比较χ2=6.6546(P<0.05),差异有统计学意义,中性对比剂组优于阳性对比剂组。结论：在MSCTE检查中,等渗中性对比剂扩张小肠的效果优于低渗的阳性对比剂,等渗中性对比剂可作为MSCTE检查的首选,但最终的选择还要根据临床的实际情况决定。%Objective:Study the application of two kinds of oral contrast agent in multislice CT enterography(MSCTE). Methods:The situation of application of oral contrast agent in 70 patiants who were checked MSCTE, 50 cases took orally neutral contrast agent-2.5%mannitol solution before the check, and 20 cases took orally positive contrast agent-diluent of iohexol. Results:Compared the degree of the expansion of duodenum、jejunum and ileum of the two groups of patients, t-value were 7.7807、6.6994 and 7.972(P<0.05), the difference was statistically significant, neutral contrast group was better than the positive contrast group. Compared the excellent rate that duodenum and ileocecal junction appeared.χ2=6.6546(P<0.05), the difference was statistically significant, the neutral contrast group was better than the positive contrast group. Conclusion:The neutral contrast was better than the positive contrast in the dilatation effects of small intestine in MSCTE check, isotonic neutral contrast can be used as the first choice in MSCTE check, But the final choice should be decided according the clinical condition.
