Correlation between values from the parametric Ki images as function of the Ki values from full kinetic analyses using the reversible 2CM (left) and irreversible 2CM (right). In blue are the data for [⁶⁸Ga]Ga-PSMA-11, in red [¹⁸F]PSMA-1007. For the analysed organs (A and B), excellent correlation is seen for [¹⁸F]PSMA-1007, whereas for [⁶⁸Ga]Ga-PSMA-11, the correlation was poor, and the multiparametric Ki values were strongly biased. For lymph node and bone lesions (C and D), excellent correlation is seen for both tracers
