Lasso algorithm for feature selection on non-enhanced phase (NP) (A, B), arterial phase (AP) (C, D), and venous phase (VP) (E, F) images. The optimal a parameters of the least absolute shrinkage and selection operator (LASSO) model were determined [NP: -log(a) = 1.16; AP: -log(a) = 1.25; VP: -log(a) = 1.11]. Features that correspond to the optimal a value were extracted.
