Exp = experiment.
Data are min⁻¹. In experiments 1 and 2, only 2 injections of ¹¹C-S12968 were performed. For estimation of myocardial blood flow, PET data were processed using 2-compartment model (plasma and tissue). Therefore, the numeric values are different from those of 3-compartment model (Table 3).
