Magnetic resonance enterography in Crohn’s disease: new simple proposal to assess disease activity.

Purpose The aim is to determine the accuracy of magnetic resonance enterography (MRE) in evaluating Crohn’s disease (CD) activity. Materials and 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. [ABSTRACT FROM AUTHOR]
