Imaging and endoscopy are essential for diagnosis and assessment of treatment response in IBD.
Cross-sectional imaging with CT and MR enterography has a key established role in mapping and assessing small bowel disease response and the main imaging modality in most centers (particularly in North America).
Ultrasound is a non-invasive, readily available modality to assess the small bowel. It doesn't require oral contrast and avoids radiation. In the correct hands it can provide exquisite bowel wall and mucosal detail (better than CT or MR in some cases).1 Secondary features of hyperemia, fat wrapping allow subjective assessment of activity. Objective measurement of disease activity with CEUS is a developing area.2
Bowel ultrasound is a fantastic tool and skill for any radiologist to have in their armoury for the assessment of IBD.
