Bowel Ultrasound State of the Art: Grayscale and Doppler Ultrasound, Contrast Enhancement, and Elastography in Crohn Disease
Jan 3, 2019 – Journal of Ultrasound in Medicine
Overall, bowel US is an excellent, safe, and repeatable choice for routine surveillance and for urgent Bowel ultrasound (US) is accurate for assessing bowel inflammation and complications in Crohn disease. Additionally, contrast‐enhanced US provides a quantitative, objective measurement of inflammatory activity in inflammatory bowel disease, and shear wave elastography predicts the stiffness of bowel, an increase of which suggests less response to medical therapy, often necessitating surgery.imaging. We describe an approach to evaluating inflammatory bowel disease and review its features on standard grayscale US with Doppler imaging and show how contrast‐enhanced US and shear wave elastography can distinguish between inflammatory and fibrostenotic bowel.
