The purpose of this study was to determine whether MRE performed with diffusion-weighted imaging (DWI) sequences is comparable to contrast-enhanced MRE in the detection of active small-bowel inflammation in pediatric patients with Crohn’s disease (CD). We included in our study 68 patients with diagnosis of CD between April 2015 and June 2018 that underwent MRE examination. Examination protocol includes coronal and axial FISP, T2-w half-Fourier RARE and DWI sequences, a baseline coronal T1-w fat-saturated ultrafast (GRE) sequence followed by contrast 3D T1-w GRE.

Objectives To evaluate the performance of Magnetic Resonance enterography (MRE) in the diagnostic work-up of children presenting with obscure gastrointestinal bleeding (OGIB). Materials and methods From January 2014 to January 2016, a single-centre prospective study was performed on all children between 0 and 16 years of age referred to the radiology department for OGIB. Each child underwent MRE examination after negative oesophagogastroduodenoscopy and ileocolonoscopy. MRE results were recorded. All patients proceeded to the related gold standard for diagnostic confirmation.
