Imaging for luminal disease and complications: CT enterography, MR enterography, small-bowel follow-through, and ultrasound.

The advent of cross-sectional enterography has revolutionized small-bowel imaging, providing comprehensive, reproducible evaluation of CD and its complications. Continued collaboration between radiologists and gastroenterologists is critical to ensure further progress toward the common goals of classifying disease activity, predicting response to treatment, and appropriate triage to medical versus surgical therapy.
