The aim of this paper is to provide indications for performing magnetic resonance enterography (MRE) in Crohn's disease (CD), the essential technical elements of MRE techniques and typical findings in patients with CD. Patients suffering from CD frequently require cross-sectional imaging. By performing MRE, it is possible to obtain results comparable to those obtained with endoscopy in terms of identifying and assessing disease activity and better than other cross-sectional imaging techniques, such as CT, in the evaluation of the fibrosis and complications of disease. The MR imaging of diffusion MR is a technique which enables medical staff to add important additional information and which may replace the use of intravenous contrast agents in the near future. Magnetic resonance enterography is an accurate tool for assessing bowel disease and the various complications associated with CD. The lack of exposure to non-ionizing radiation is an important advantage of this imaging technique, especially in the case of pediatric patients. Familiarity with common and pathognomonic imaging features of CD is essential for every clinician involved in the treatment of inflammatory bowel disease and the care of patients.
本文旨在为克罗恩病（CD）患者提供磁共振肠造影（MRE）的检查指征、MRE 技术的基本技术要点以及 CD 患者的典型表现。患有 CD 的患者经常需要进行横断面成像。通过进行 MRE，可以获得与内镜检查相当的结果，在识别和评估疾病活动方面优于 CT 等其他横断面成像技术，在评估纤维化和疾病并发症方面更是如此。磁共振弥散成像技术是一种能够为医务人员提供重要附加信息的技术，并且在不久的将来可能会替代静脉内造影剂的使用。磁共振肠造影术是一种评估肠道疾病和与 CD 相关的各种并发症的准确工具。这种成像技术的一个重要优点是没有非电离辐射，特别是在儿科患者中。熟悉 CD 的常见和特征性影像学表现对于参与炎症性肠病治疗和患者护理的每位临床医生来说都是必不可少的。
