Table 4 Impact of phantom calibration, as given by the % difference of each database before and after calibration

From: [123I]FP-CIT ENC-DAT normal database: the impact of the reconstruction and quantification methods

SBR % difference:
phantom calibration
BRASS Southampton
FBP (post-pre) 96.0 27.8
IRNC (post-pre) 102.1 33.6
ACSC (post-pre) 67.4 −0.2
  1. With ACSC, this difference represents the phantom recovery of partial volume losses, which is significant for BRASS but not for the Southampton method (p = 0.44)
  2. SBR striatal specific binding ratio
