Figure 6: Receiver operating characteristic curves using calprotectin levels to determine active versus nonactive disease with MaRIA (a), MaRIA and ADC (b), and MaRIA, ADC, and MIV (c) as the variables. MaRIA: magnetic resonance index of activity; ADC: apparent diffusion coefficient. MIV: metabolic inflammatory volume.
