Overview

Transabdominal intestinal ultrasound (IUS) is gaining acceptance as a point-of-care test to objectively assess disease activity in Crohn's disease (CD).

In order to incorporate individual parameters in a future definition of transmural healing, and for the consistent application of IUS as a modality to assess treatment outcomes and establish therapeutic targets to ensure comparability between future studies, the inter-observer agreement should be determined for all relevant parameters.
