Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 16 and older with small bowel or colonic Crohn's disease who have already undergone baseline imaging.

Probably not a fit

Patients who have had surgical resection of affected bowel segments or those unable to provide informed consent will not benefit from this study.

What this trial studies

This observational study aims to evaluate the diagnostic concordance between MR Enterography (MRE) and Intestinal Ultrasound (IUS) in assessing treatment response in patients with Crohn's disease. It focuses on patients aged 16 and older who have undergone baseline imaging and require follow-up imaging to determine the effectiveness of their treatment. The study seeks to address the variability in imaging modality selection and provide clearer guidance on the use of MRE and IUS for treatment assessment. By comparing these two non-invasive imaging techniques, the study hopes to improve patient management and reduce reliance on more invasive procedures.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and patient-preferred methods for assessing treatment response in Crohn's disease.

How similar studies have gone: While there is limited literature on this specific comparison, previous studies have shown both MRE and IUS to be effective for diagnosing Crohn's disease, indicating potential for success in this approach.
