Magnetic resonance enterography in post-operative inflammatory bowel disease

Authors: Jeffrey S. Quon, Phillip R. Quon, Christopher S. Lim, Nishard Abdeen, Nicola Schieda

Published in: Abdominal Radiology | Issue 5/2015

Abstract

Objective

To describe the role of magnetic resonance enterography (MRE) in patients with inflammatory bowel disease (IBD), and to review the expected post-operative appearance, as well as, potential surgical complications in this unique patient population.

Conclusion

MRE compares favorably to CT Enterography (CTE) in terms of overall diagnostic accuracy and may provide better functional assessment of the small bowel through cine-MRI, diffusion-weighted imaging and dynamic contrast-enhancement. In the post-operative population, MRE provides critical information including: normal post-surgical anatomy, chronic strictures vs. active inflammation and disease/treatment-related complications. The post-operative IBD patient undergoes frequent repeated imaging and MRE may significantly reduce cumulative radiation dose while providing similar or improved diagnostic accuracy compared to CTE. MRE should be considered as an alternative imaging modality in this population.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
