Diagnostic accuracy of predictive MRE scores for histologic fibrosis and inflammation, Fibrosis_MRE and MaRIA, respectively, for detection of moderate to severe fibrosis and inflammation and active inflammation

	ROCAUC	Cutoff	Sensitivity	Specificity
Fibrosis moderate/severe (FibrosisMRE)	0.910	≥2.080	0.681	1.000
Fibrosis moderate/severe (MaRIA)	0.896	≥8.857	0.958	0.733
Fibrosis moderate/severe (ADC)	0.894	≥1.452	0.958	0.692
Inflammation mod/severe (MaRIA)	0.763	≥18.085	0.731	0.686
Inflammation active (MaRIA)	0.966	≥7.120	0.926	1.000

AUC, area under curve; ADC, apparent diffusion coefficient; MRE, magnetic resonance enterography; MaRIA, magnetic resonance index of activity; ROC, receiver operator characteristic.

Fibrosis_MRE was a very good predictor of moderate to severe histological fibrosis. MaRIA had excellent performance in detecting active histological inflammation.
