The investigators compared magnetic resonance imaging (MRI) of the abdomen with ultrasound of the abdomen and gastrointestinal tract in patients with Crohn's disease.
They published their findings in the June issue of European Radiology.
A total of 46 patients were included in the retrospective study.
The localization of Crohn's lesions, the number of affected bowel segments, and the number of stenoses were all analyzed.
The presence of abscesses, fistulae, and any additional findings were also documented.
Findings were verified by means of one or more of the following: enteroclysis, surgical findings, and colonoscopy.
The results showed that MRI is superior to ultrasound in the localization of affected bowel segments (sensitivity: 98% vs 76%).

MRI was also found to be better in recognizing fistulae (sensitivity: 87% vs 31%), stenoses (100% vs 58%), and abscesses (100% vs 89%).
Author S. Potthast, of the University of Ulm, said on behalf of the group, "MRI of the abdomen should be obtained to clarify discrepant clinical and sonographic findings."
"In addition, despite its higher cost, MRI of the abdomen is justified in patients in whom Crohn's lesions are known or suspected in anatomic areas proximal to the terminal or neoterminal ileum.
"It is also appropriate in cases with suspicion of fistulae and abscesses," it was concluded.
