  1. Protocols with better summary data quality measures are given higher scores.
  2. Criteria:
  3. Euler No : the less negative the better,
  4. Grey/white CNR: the bigger the better,
  5. Grey/CSF CNR : the bigger the better,
  6. Total CNR : the bigger the better.
  7. * The MRI protocols taken forward to the next step.
