Shooting a Moving Target: Use of Real-Time Cine Magnetic Resonance Imaging in Assessment of the Small Bowel

ABSTRACTThe chronic nature of inflammatory bowel disease (IBD) creates a lifelong effect on the morbidity of children affected by the disease. The ability to confidently identify and characterize complications resulting from IBD in the pediatric patient is of critical importance. Magnetic resonance enterography (MRE) is especially valuable in the diagnostic assessment of IBD; however, precise elucidation of complications including strictures can be difficult with standard MRE sequences. The recent development of faster MRI pulse sequences provides rapid, real-time imaging of the intestinal tract. In this review, we describe how the addition of cine MRE confidently pinpoints areas of stricture, aids in lesion detection and diagnosis, and provides valuable information on intestinal motility.
