摘　　要：目的 探讨自配口服低浓度阳性对比剂在腹部肿块与小肠关系的鉴别诊断中的应用价值.方法 收集CT检查小肠袢间需要鉴别肠壁肠外肿块的病例,口服对比剂后再进行MSCT扫描,口服浓度为0.6%阳性对比剂的共49例为A组（评价组）,另一组口服2.5%等渗甘露醇溶液的共40例作为B组（对照组）,以是否能在影像上识别肿块与小肠的关系为标准,比较2组病例识别率的差异.结果 2组病例在肠外和肠壁肿块的识别率方面,评价组（95.92%）明显高于对照组（65%）,差异具有统计学意义（P＜0.01）.结论 口服对比剂（0.6%碘剂稀释液）在鉴别腹部肿块与小肠的关系上,比阴性对比剂（2.5%等渗甘露醇溶液）有更好鉴别诊断效果.Objective To study the wllue of low-concentration positive oral contrast agent MSCT in showing the relationship be tween abdominal masses and the small intestinal masses. Methods 89 cases of abdominal masses underwent CT examinations. 69 cases were divided into two group： group A（49 cases） administered orally 0.6% positive contrast agents and group B（40 cases） was administration of 2.5 % isotonic mannitoI solution. The relationship between the masses and the small intestine were comparatively evaluated by CT in group A and I4. Results In differentiating the extraintestinal masses from intraintestinal masses by CT,there was statistical significance （P〈0.01） between group A（95.92 % ） and group B（65 % ）. Conclusion In the identification of the relaionship between the abdominal mass and the small intestine with CT,the positive contrast agent orally （0.6% iodine dilute solution） is more effective than negative contrast agent （2.5 % isotonic mannitol solution）.
