Representative Images of Primary Outcomes. A) Coronal single shot fast spin echo T2 weighted MR enterography (MR-E) image demonstrates a loop of terminal ileum with wall thickening, luminal narrowing, and adjacent fluid within the right lower quadrant (arrow). B) Coronal post-contrast T1 weighted fat-saturated (FS) MR-E image demonstrates the same loop of inflamed terminal ileum with mural hyper enhancement and an adjacent enhancing phlegmon with foci of gas (arrow). There is also a small amount of fibrofatty proliferation. C) Coronal post-contrast T1 weighted FS MR-E image demonstrates a loop of mid-jejunum with mucosal hyper enhancement, mural stratification, luminal narrowing, and adjacent engorgement of the vasa recta (arrow) with proximal dilated segment (dashed arrow) indicating a stricture. D) Axial post-contrast T1 weighted FS MR-E image demonstrates an ileal to appendiceal tip fistula with mild bowel wall thickening (arrow). Note: Images 1A-C are from the same patient over the course of 11 months. Patient underwent two surgeries for jejunal, proximal ileal, and distal ileal stricture (with distal ileal abscess).
