MRE vs colonoscopy for skip lesions in suspected Crohn's colitis

What is known

• The excerpts characterize MRE performance for Crohn's-related bowel stenosis, abscess, small-bowel lesions, and postoperative recurrence ^1–3.
• MRE is described as radiation-free cross-sectional imaging comparable to CT enterography in diagnostic accuracy ⁴.

What is unknown / caveats

• No retrieved study answers this specific comparison.
• None report the sensitivity of MRE versus colonoscopy for detecting skip lesions.
• None stratify that comparison by Crohn's colitis versus ulcerative colitis.
