Primary Outcome Measures:
  • Follow-up of known small bowel Crohn disease [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    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.


Estimated Enrollment: 50
Study Start Date: March 2012
Estimated Study Completion Date: August 2016
Estimated Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Pediatric small bowel Crohn disease
Subjects with previously diagnosed PSBCD (pediatric small bowel Crohn disease)who are scheduled for a clinically MRE (magnetic resonance enterography)imaging exam.
Procedure: Bowel ultrasound
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.
Other Names:
  • abdominal ultrasound imaging
  • ultrasound elasticity imaging
Procedure: magnetic resonance enterography (MRE)
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.

Detailed Description:

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.
