Continuous response measurements

Positive values for ΔADC, ΔnADC and ΔSTIR represent improving inflammation, whereas negative values represent worsening inflammation. ADC: apparent diffusion coefficient; nADC: normalized apparent diffusion coefficient; STIR: short tau inversion recovery; ΔADC: change in ADC after therapy; ΔnADC: change in nADC after therapy; ΔSTIR: change in STIR score after therapy.
