  1. Mean RSD of the RCs for the 15 repeats per reconstruction protocol and across all reconstruction protocols for SUVmax, SUVref and SUVpeak. Reduction in RSD with both SUVref and SUVpeak for all intra-reconstruction protocol comparisons, in addition to across all protocols, was significant (P < 0.01 with paired two-tailed Student's t-test).
