  1. The difference of the un-calibrated Southampton and BRASS databases (first row) represents the magnitude of partial volume losses in human studies. The limitation of phantom calibration in compensating for this effect is reflected in the residual differences of the post-calibration databases
  2. SBR striatal specific binding ratio
