Boxplots of percentages of dose difference (PDD) between absorbed doses estimated with the Missing Time-Point method (M1) at 24H and absorbed doses estimated with the reference method (tri-exponential function for fitting TDRC) for each VOI: LK, RK, L, S, L2 to L4, L1 to L5 and T9 to L5. Each boxplot includes PDD of the patient cohort at 24H (only cycles with three SPECT/CT acquisitions as shown in Table 1) and PDD of the validation cohort at 24H of cycles 1 and 4. For the two other time-points (6H in red and 7D in blue), PDD are estimated from the validation cohort only (cycles 1 and 4), and the mean and the median are represented by triangles and circles, respectively
