title: Magnetic resonance enterography in Crohn's disease: new simple proposal to assess disease activity.
abstract: OBJECTIVE
  The aim is to determine the accuracy of magnetic resonance enterography (MRE) in evaluating Crohn's disease (CD) activity.
  
  
  METHODS
  Seventy-seven patients with CD underwent MRE. The primary analysis was to determine associations between MRE findings, Harvey-Bradshaw Index, and C-reactive protein (CRP), then we have created a new MRE score that it was also correlated with clinical and laboratory data.
  
  
  RESULTS
  MRE score for CD significantly correlates with CRP (P=.003). Significant associations were found between degree of contrast enhancement and CRP (P=.002) and between comb sign and CRP (P=.001).
  
  
  CONCLUSIONS
  These results make MRE an important instrument for evaluation of CD activity.
