目的 评估充盈法在多层肠道CT 诊断大小肠炎症性肠病中的价值。方法 回顾性分析3年来我院收治的75例炎症性 肠病患者的临床资料，随机分成三组， A组使用常规法充盈，B、C组使用我院改 良后的方法进行充盈，经MSCT成像后， 观察对比充盈后3组患者的舒适度，图像 中肠管扩张程度，各部分图像质量，疾 病表现情况。结果 观察对比3组患者的 数据，发现B、C组在舒适度上效果明显 好于A组。图像中肠管扩张程度，各部 分图像质量，疾病表现情况C组均好于B 组，B、C组又都好于A组。结论 我院改 良后的充盈方法使MSCT成像更清晰，不 但可以清晰显示大小肠肠壁情况，还可 以显示大小肠病变和并发症情况，可以 提高炎症性肠病诊断的准确率。

Objective Assessment of filling method in multilayer bowel CT diagnostic value in large intestinal inflammatory bowel disease. Methods 3 years in our hospital were retrospectively analyzed the clinical data of 75 cases of inflammatory bowel disease, randomly divided into three groups, using the conventional method of group A filling, group B and C using our modified method for filling, after MSCT,three groups of patients after observation contrast filling comfort, in the image insufflate expansion degree, each part of the image quality, disease present situation. Results Data contrast of three groups of patients, effect on comfort found that B and C group was obviously better than that of group A. In the image insufflate expansion degree, each part of the image quality,disease present situation are better than that of group B, group C, B and C group were better than that of group A. Conclusion Our modified filling method makes MSCT imaging is more clear, not only can clear display large intestine intestinal wall, can also show large intestine pathological changes and complications, can improve the accuracy of inflammatory bowel disease diagnosis.
