(a) Coronal T2-weighted and (b) coronal T1-weighted fat-saturated postgadolinium images demonstrating wall thickening and hyperenhancement of the terminal ileum (arrows). (c) Coronal -weighted image depicts nanoparticle accumulation in the wall of the cecum and ascending colon (low signal indicated by the arrowheads) indicating inflammatory involvement not visible on conventional MR sequences.
