International Bowel Ultrasound Group
Treatment targets for IBD have evolved beyond clinical symptoms and remission. The recognition of the importance of healing seen on cross-sectional imaging modalities, including ultrasound is growing, predictive of improved outcomes for patients. IUS is cost-effective, well tolerated by patients and thus easily repeatable. This creates a perfect monitoring tool, yet access to this important innovation is limited in many parts of the world. Increasing the scientific evidence foundation to support the use of IUS is imperative to increase uptake.
Intestinal Ultrasound Standardized
Topics & Key Questions
The aim of this publication, is to provide standardized guidance to expert clinicians regarding image acquisition during intestinal ultrasound assessment with the intent of centralized reading (for example, for the purpose of evaluation during clinical trials). The purpose is to best standardized image acquisition, to improve consistency in interpretation.
- Image Acquisition Guidelines
- Bowel wall thickness
- Mesenteric, inflammatory fat
- Color Doppler Imaging
