Gut malrotation is a congenital disorder of abnormal intestinal rotation, for which the current diagnostic technique is an upper GI X-ray contrast study. This study evaluated the feasibility of interactive MR fluoroscopy for defining the gastro-intestinal tract anatomy in un-sedated children with suspected malrotation. We imaged 9 children using both X-ray fluoroscopy, FIESTA and interactive SSFSE MR imaging. We confidently identified the DJ flexure (7/9; 77%), orientation of the SMA / SMV (8/9; 88%) and the caecum (9/9; 100% using MRI. Interactive MR Fluoroscopy is feasible for gut imaging in un-sedated children.
