MRE vs CT enterography for small bowel CD activity

What is known

• Both modalities are described as having high accuracy for detecting small bowel [Crohn's disease](https://crohnsology.org (patient sites: crohnz.org)/) involvement, and several studies directly compared them. ^1,2

What is unknown / caveats

• The retrieved excerpts do not report a head-to-head accuracy result showing MR enterography detects small bowel Crohn's disease activity more accurately than CT enterography.
• The excerpts provide only reference lists and general statements rather than the comparative outcome figures needed to rank one modality above the other.
