Crohn's disease begins in childhood in 20% of cases. Imaging of the small bowel is needed for diagnosis and management and also to inform the clinician of the location, extent, and activity of disease. There are several modalities available to image the small bowel and the combined use of these is often required to optimise benefit. Methods available for imaging the small bowel include barium studies, sonography, CT, wireless capsule endoscopy, nuclear medicine studies, and MRI. Patient comfort is paramount in imaging paediatric patients. Therefore, non-invasive techniques are most likely to be successful. Furthermore, as children are at greatest risk of radiation induced malignancy, modalities which do not carry a radiation burden are preferable. This article discusses the methods available for imaging the small bowel in paediatric Crohn's disease and the relative merits of each modality.
20%的儿童克罗恩病始于童年。为了诊断和治疗，并向临床医生提供疾病的位置、范围和活动情况，需要对小肠进行成像。有几种方法可以对小肠进行成像，通常需要结合使用这些方法以最大限度地发挥其益处。可用于小肠成像的方法包括钡剂研究、超声、CT、无线胶囊内镜、核医学研究和 MRI。在对儿科患者进行成像时，患者的舒适度至关重要。因此，非侵入性技术最有可能成功。此外，由于儿童患放射性致癌的风险最大，因此最好选择没有辐射负担的方法。本文讨论了儿童克罗恩病小肠成像的可用方法以及每种方法的相对优点。
