Comparison of Bowel Ultrasound & MR Enterography in the Follow-up of Previously Diagnosed Pediatric Small Bowel Crohn Disease

Children's Hospital Medical Center, Cincinnati33 enrolled

Overview

To establish the accuracy of bowel ultrasound in the follow-up of known (previously diagnosed) pediatric small bowel Crohn disease, using MR Enterography (magnetic resonance imaging technology used to obtain detailed images of the small bowel) as the reference standard.

25-30% of individuals with Crohn disease present during childhood or adolescence, and the incidence is rising. MRE (magnetic resonance enterography) is considered the standard of care for imaging of pediatric small bowel Crohn's disease. Bowel ultrasound is an emerging technology for bowel assessment and offers several advantages over MRE, including lower cost, shorter exam time, and lack of need for sedation and contrast materials and bowel medication. The researchers goal is to assess the accuracy of bowel ultrasound in the follow-up of known pediatric small bowel Crohn disease using MRE and the reference standard.

Interventions

Bowel ultrasoundPROCEDURE

The ultrasound imaging will take place prior to the clinically ordered MRE exam. The subject will be asked to lie on the ultrasound table for approximately 60 minutes while a variety of ultrasound images are completed.

magnetic resonance enterography (MRE)PROCEDURE

The subject will have a small intravenous (IV) catheter placed in on of their arms before the MRE exam. Medications called Glucagon and MultiHance will be given thru the IV catheter during the imaging study. The glucagon will decrease the movement of the intestines, which helps provide better images of the bowel. MultiHance is a contrast that helps create clearer MRE images. In addition to the MultiHance, the subject will be given an oral contrast medication called VoLumen to drink approximately 45 minutes before the MRE imaging is started. These medications are used for all clinically necessary MRE studies performed in children and adults at the UMHS. The MRE will take approximately 50 to 60 minutes to complete.

Outcomes

Primary Outcomes

Follow-up of known small bowel Crohn disease

A variety of imaging findings will be documented by ultrasound and correlated with the imaging findings from the clinically ordered MRE exam to determine the efficacy of bowel ultrasound in the follow-up of small bowel Crohn disease in pediatric subjects.
