Figure 4: Receiver operating characteristic curves using calprotectin and CRP levels to determine active versus nonactive disease with MaRIA (a), MaRIA and ADC (b), and MaRIA, ADC, and MIV (c) as the variables. CRP: C-reactive protein; MaRIA: magnetic resonance index of activity; ADC: apparent diffusion coefficient; MIV: metabolic inflammatory volume.
