Hepatocellular carcinoma <sup>18</sup> F‐FDG PET/CT kinetic parameter estimation based on the advantage actor‐critic algorithm

Compared with the conventional postreconstruction NLLS method, the A2C algorithm can more precisely estimate <sup>18</sup>F-FDG kinetic parameters with a reversible double-input, three-compartment model for HCC tumors, attaining better TAC fitting with a lower RMSE.
