Magnetic resonance (MR) imaging is rapidly increasing clinical acceptance to evaluate the small bowel and can be the initial imaging method to investigate small bowel diseases. MR examinations may provide the first opportunity to detect and characterize tumours of the small bowel. Intra- and extraluminal MR findings, combined with contrast enhancement and functional information, help to make an accurate diagnosis and consequently characterize small bowel neoplasms. MR enteroclysis should be recommended for the initial investigation in patients suspected of having small bowel tumours. In this article, the MR findings of primary small bowel neoplasms are described and the MR findings for the differential diagnosis are discussed.
磁共振（MR）成像技术在评估小肠方面迅速得到临床认可，并且可以作为初步的成像方法来检查小肠疾病。MR 检查可能提供首次发现和诊断小肠肿瘤的机会。腔内和腔外的 MR 表现，结合增强和功能信息，有助于做出准确的诊断，从而对小肠肿瘤进行分类。对于疑似患有小肠肿瘤的患者，应推荐进行 MR 肠造影检查作为初始检查。本文描述了原发性小肠肿瘤的 MR 表现，并讨论了鉴别诊断的 MR 表现。
