Figure 7. Correlation heatmaps of selected features. (A) Correlation matrix heatmap of the 12 selected features in the PP-DL model; (B) Correlation matrix heatmap of the 11 selected features in the PP-DLR model; (C) Correlation matrix heatmap of the 11 selected features in the CP-radiomics model; (D) Correlation matrix heatmap of the 7 selected features in the CP-DLR model. PP: Portal venous phase; DL: deep learning; DLR: deep learning radiomics; CP: combined phase. PP: Portal venous phase; DL: deep learning; DLR: deep learning radiomics.
