In more than 20% of all patients, the Crohn's diseasepresents before the age of 18 years. The diagnosisand management of Crohn's disease in children haschanged dramatically over the last decade, mainly dueto increased awareness, availability of newer diagnosticmodalities such as magnetic resonance imaging(MRI)and newer, more powerful treatments such as biolog-ics. Imaging of the small bowel is needed for diagno-sis, management, follow-up and also evaluation of thedisease in terms of location, extent, activity and com-plications. We review all the methods(barium exami-nations, ultrasonography, computed tomography, MR,and computed tomography- positron emission tomog-raphy) commonly used for imaging the small bowel inpaediatric patients with Crohn's disease analyzing theadvantages and disadvantages of each modality, withparticular emphasis on MR imaging.
