  1. DWI (all b values and ADC maps) and T1-w Dixon (fat- and water-only maps) images from all stations were assessed radiologically on a 4-point Likert scale: 1 = non-diagnostic; 2 = sub-optimal; 3 = good; 4 = excellent
  2. * Example of clinical patient for MR protocol testing (patient not within trial)
