Table 3 Metrics for agreement of simultaneously estimated and blood-sampled input functions without simulation of spillover

From: Estimation of input functions from dynamic [18F]FLT PET studies of the head and neck with correction for partial volume effects

  Init BSIF Init PET
  Number of samples Number of samples
  0 1 2 3 0 1 2 3
RMS norm 3.5 2.0 (0.4) 1.3 (0.9) 1.1 4.2 2.4 (0.4) 1.1 (0.4) 1.2
Peak AUC (%) 31 40 (11) 16 (11) 11 43 37 (6) 26 (9) 14
Tail AUC (%) 58 38 (9) 11 (24) 14 104 54 (15) 18 (14) 15
  1. Median (median interquartile range) of RMSnorm values and errors of the area under the peak and tail of the estimated input function, as the moduli of the percentages of the areas under the blood-sampled input function (calculated without simulation of spillover).
