What is Intestinal Ultrasound (IUS)?
Intestinal Ultrasound (IUS) is a non-invasive, real-time ultrasound examination of the bowel wall performed in the clinic setting. Using a high-frequency ultrasound probe placed on the abdomen, the gastroenterologist can visualise and assess the thickness and characteristics of the bowel wall, vascularity, and surrounding structures.
IUS has emerged as a powerful monitoring tool for inflammatory bowel disease (IBD), offering a quick, radiation-free, and well-tolerated method to assess disease activity and treatment response without the need for endoscopy or cross-sectional imaging.
When is IUS Used?
- Monitoring disease activity in Crohn’s disease or Ulcerative Colitis
- Assessment of treatment response to IBD therapies
- Identification of complications such as strictures, fistulas, or abscesses
- Guiding treatment decisions between consultations
- Assessing transmural healing as a therapeutic target
- Differentiation of active inflammation versus fibrosis in Crohn’s
- Point-of-care assessment during flares or clinical deterioration
What to Expect
No Preparation Required
IUS requires no fasting, bowel preparation, or sedation. It can be performed at your regular consultation.
Gel Application
Ultrasound gel is applied to the abdomen, similar to a standard abdominal ultrasound examination.
Real-Time Assessment
The probe is moved across the abdomen to assess different bowel segments. The examination is painless for most patients.
Immediate Results
Findings are discussed with you immediately during or after the consultation, allowing real-time clinical decision-making.
