Fig. 2

Scatchard plots of the simulation study in the a CP (a high-binding VOI) and b VTA (a low-binding VOI) for various masses of the injected unlabeled ligand. Note that a dose of the unlabeled ligand of 3 ug/kg or higher produces a Scatchard plot in both VOI. The dose of 3 ug/kg produces a Scatchard plot with the highest range of C_S/C_ND values
