Correct answer: E — MR enterography

MR enterography is the preferred imaging modality for assessing small bowel Crohn's disease in children. It provides detailed mucosal and transmural assessment without ionising radiation. CT is avoided in children due to radiation exposure. Capsule endoscopy may be used when MR enterography is non-diagnostic but carries a risk of capsule retention in stricturing disease.
