Table 1 Inter- and intra-observer reliability of quantitative parameters

From: Exercise-induced muscle damage: multi-parametric MRI quantitative assessment

Parameter Inter-observer Reliability Intra-observer Reliability
Observer 1 Observer 2
ADC 0.943 0.971 0.929
T2 0.905 0.921 0.893
FA 0.933 0.939 0.947
D 0.874 0.928 0.864
D* 0.881 0.824 0.906
  1. ICC values ranged from 0 to 1, less than 0.4 indicating poor reliability, and greater than 0.75 indicating good reliability
  2. ADC apparent diffusion coefficient, T2 transverse relaxation time, FA fractional anisotropy, D true diffusion coefficient; D* pseudo-diffusion coefficient
