摘　　要：目的:探讨MRI对小肠疾病的诊断价值。方法:28例患者行小肠MRI检查,其中19例同期行小肠钡灌肠检查。所有24例小肠病变患者中13例经手术证实,1例血管性病变经DSA造影证实,另10例均结合临床病史作出诊断,并对MRI各种检查序列进行了比较。结果:在显示肠腔狭窄、肠外压迹方面,MRI与小肠钡灌肠的差异没有显著性意义(P>0．05)。在显示肠壁肿块和增厚方面,MR优于小肠钡灌肠检查(P<0．05和P<0．01)。MRI各序列在显示肠壁异常改变、肠腔狭窄、肠外压迹和粘膜异常方面,差异存在显著性意义(P<0．05)。结论:MRI能更好地显示小肠病变时肠壁及系膜改变,弥补了小肠钡灌肠检查的不足。Objective：The purpose of this study was to evaluate the diagnostic value of the MR imaging of the small bowel disease. Methods：28 patients underwent MRI examination of small bowel. Of them, 19 patients had small-bowel enteroclysis （SBE） and 10 patients had CT scans. Of these 24 patients with small bowel disease, 11 cases had surgery and proved by pathology,1 case was diagnosed by DSA, the others were diagnosed by clinical history and symptoms only. The results of these 3 modalities as well as different MR sequences were compared. Results：There were no significant difference between MRI and SBE in showing howel constriction, extra-luminal compression （P〉 0.05）, MRI was superior to SBE in showing mass and mural thickening （P〈0. 005）. There is no significant difference between different sequences of MRI in showing mural abnormalities, bowel constriction, extra-luminal compression and mucosal lesion. Conclusion： Bowel wall and mesenteric abnormalities can be better revealed and the shortage of SBE can be made up by MRL
