Latest Intestinal Ultrasound Advancements In Inflammatory Bowel Disease


  • Cathy Lu, MD, MSC Division of Gastroenterology and Hepatology, University of Calgary, Calgary, Alberta



Inflammatory bowel disease (IBD) treatment has evolved from monitoring clinical symptoms to targeting objective measurements of mucosal healing with endoscopic and radiologic imaging. It is well known that clinical symptoms do not match disease severity. Frequent evaluation with radiologic imaging is now the standard of care. Although Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE-II) recommendations do not list radiographic targets as an endpoint due to the “limited ability of the currently available treatments to achieve transmural healing,” this will likely evolve over time particularly with the rapidly growing uptake of intestinal ultrasound (IUS) in clinical trials. For the time being, imaging is considered as an “adjuvant assessment rather than a formal treatment target.”

Cathy Lu, MD, MSC, Division of Gastroenterology and Hepatology, University of Calgary, Calgary, Alberta

Dr. Cathy Lu is a gastroenterologist and Assistant Professor at the University of Calgary. She completed a joint two year advanced IBD fellowship at the University of Alberta and the University of Calgary with specialization in intestinal ultrasound. She is an operational committee board member of the STAR (Stenosis, Therapy, and Anti-Fibrotic Research) Consortium and leads the development of the ultrasound index for Crohn’s disease strictures. She has also served as a member of the scientific committee for IBUS (the International Bowel Ultrasound Organization) and the Canadian Association of Gastroenterology. Dr. Lu currently co-chairs the scientific committee of iUS-CAN, the United States and Canada consortium for IUS. Her primary research interests are in fibrostenotic Crohn’s disease, intestinal ultrasound, and translational research identifying biomarkers in diagnosis, monitoring, and treatment response in IBD.
