“…Timing of oral contrast in relation to image acquisition has been the subject of multiple studies [ 51 , 56 , 66 ]. Generally, it is recommended that oral contrast ingestion start 45–60 min prior to MRE image acquisition [ 56 ]. For example in one study, optimal small bowel distension was achieved in all 16 healthy volunteers who commenced oral contrast ingestion 45–60 min prior to MRE image acquisition, yet a significant loss of distension was seen in the duodenal and proximal jejunal segments when oral contrast ingestion was extended to 75 min prior to image acquisition [ 66 ].…”

“…Rectal filling with water has been performed in studies assessing the ability of MRE to also incorporate colonic CD assessment [ 50 , 56 , 65 ]. Along with improvement in large bowel distension, studies have demonstrated a significant improvement in small bowel distension with the application of a rectal enema/instillation of fluids via catheter and subsequent improved detection of CD-related changes in the small bowel [ 70 ].…”

Magnetic resonance enterography (MRE) is one of the most highly utilised tools in the assessment of patients with small bowel Crohn’s disease (CD). As a non-invasive modality, it has both patient and procedure-related advantages over ileocolonoscopy which is the current gold standard for Crohn’s disease activity assessment. MRE relies upon high-quality images to ensure accurate disease activity assessment; however, few studies have explored the impact of image quality on the accuracy of small bowel CD activity assessment. Bowel distension and motion artifacts are two key imaging parameters that impact the quality of images obtained through MRE. Multiple strategies have been employed to both minimise the effects of motion artifacts and improve bowel distension. This review discusses the definitions of bowel distension and motion artifacts within the literature with a particular focus on current strategies to improve bowel distension and limit motion artifacts in MRE.

Background: Crohn’s disease (CD) is a chronic, progressive inflammatory condition, involving primarily the bowel, characterized by a typical remitting–relapsing pattern. Despite endoscopy representing the reference standard for the diagnosis and assessment of disease activity, radiological imaging has a key role, providing information about mural and extra-visceral involvement. Methods: Computed Tomography and Magnetic Resonance Imaging are the most frequently used radiological techniques in clinical practice for both the diagnosis and staging of CD involving the small bowel in non-urgent settings. The contribution of imaging in the management of CD is reported on by answering the following practical questions: (1) What is the best technique for the assessment of small bowel CD? (2) Is imaging a good option to assess colonic disease? (3) Which disease pattern is present: inflammatory, fibrotic or fistulizing? (4) Is it possible to identify the presence of strictures and to discriminate inflammatory from fibrotic ones? (5) How does imaging help in defining disease extension and localization? (6) Can imaging assess disease activity? (7) Is it possible to evaluate post-operative recurrence? Results: Imaging is suitable for assessing disease activity, extension and characterizing disease patterns. CT and MRI can both answer the abovementioned questions, but MRI has a greater sensitivity and specificity for assessing disease activity and does not use ionizing radiation. Conclusions: Radiologists are essential healthcare professionals to be involved in multidisciplinary teams for the management of CD patients to obtain the necessary answers for clinically relevant questions.
