  1. ADC Apparent diffusion coefficient, MC Modic change. MC-ADC, ADC in MC. MC-ADC%, ADC in MC in percent (0% = vertebral body, 100% = cerebrospinal fluid). MC-ADC-ratio, ADC in MC divided by ADC in normal vertebral body marrow
  2. Values are intraclass correlation coefficients (95% confidence intervals)
