Comparison of Magnetic Resonance Enterography With Endoscopy, Histopathology, and Laboratory Evaluation in Pediatric Crohn Disease
Journal of Pediatric Gastroenterology and Nutrition, 08/02/2012
Sauer CG et al. – Active inflammation on Magnetic resonance enterography (MRE) is associated with higher C–reactive protein, erythrocyte sedimentation rate, platelets, and lower albumin in children with CD. MRE displays excellent agreement with endoscopic disease described by ulcers but poor agreement with mild mucosal disease described by erythema and friability. The present study adds to a growing body of evidence that MRE provides excellent assessment of inflammation and measures disease activity in CD.Methods
- The authors performed an institutional review board–approved query of prospective CD MRE database, which includes data in children with CD undergoing MRE since 2008.
- A total of 147 MRE studies were performed in 119 different children with symptomatic CD.
- Of those, 53 (39.6%) MRE studies were performed at diagnosis to evaluate small bowel disease burden.
- A total of 117 (79.6%) MRE studies displayed active and/or chronic disease, whereas 30 (20.4%) MRE studies were normal.
- When compared with normal MRE studies, active inflammation on MRE was associated with a higher mean C-reactive protein (3.6 vs 1.1, P<0.001), higher erythrocyte sedimentation rate (36 vs 22, P=0.0.31), higher platelet value (439 vs 352, P=0.033), and lower albumin (3.4 vs 3.7, P=0.049).
- Comparison between MRE and endoscopy demonstrated excellent agreement when ulcers were present, and moderate agreement with histopathology.
