Cure8 news brief
This study supports intestinal ultrasound as a noninvasive, accurate way to detect small-bowel Crohn's activity in many pediatric patients, which could reduce reliance on MRI for routine monitoring. It highlights specific bowel wall thickness cutoffs that may help interpret IUS in children.
Pediatric IBD clinicians and sonographers; parents and caregivers of children with Crohn's disease; researchers interested in noninvasive monitoring.
A team in Amsterdam enrolled 78 children with Crohn's disease who had IUS and MRE within a week. Certified ultrasonographers performed blinded IUS and measured BWT and other ultrasound features.
Using MRE as the reference, the study reported excellent performance for IUS BWT in the terminal ileum (AUC 0.91) and very good performance in the proximal ileum (AUC 0.80). Optimal BWT cutoffs for detecting activity were 2.4 mm (terminal ileum) and 2.0 mm (proximal ileum).
The jejunum showed lower diagnostic performance and no reliable BWT cutoff was established. The authors suggest IUS (with BWT measurement) could be integrated as a first-line, noninvasive tool to assess small-bowel disease activity in children, while acknowledging lower accuracy in the jejunum and that only B-mode IUS was assessed.
Medscape's article summarizes a peer-reviewed prospective study using MRE as the reference. IUS performance was lower for the jejunum, the study used B-mode only, and imaging techniques and operator experience can affect results. The original paper in Journal of Pediatric Gastroenterology and Nutrition should be consulted for full methods and limitations.

Children with Crohn's and their clinicians often need noninvasive, accessible ways to monitor small-bowel disease. If validated elsewhere, IUS with the reported BWT thresholds could reduce reliance on MRE, which is...
A multimodal, simpler activity score could improve practical disease monitoring when full ileocolonoscopy isn’t possible and help standardize treat-to-target practice across centers.
This study could clarify which imaging test—MRE or IUS—is more accurate or appropriate for monitoring treatment response in Crohn's disease, potentially standardising follow-up and informing patient and clinician...
