Figure 4.

Representative slices from the CT and ¹⁸F-FDG PET scans of three lesions with a diverse range of radiomics features and TBR_max. Each subfigure corresponds to a different lesion, with the CT scan on the left panel and the ¹⁸F-FDG PET scan on the right panel. The main features for each lesion are: (a) TBR_max=1.5, $V_{>70}^{\downarrow }$ =35 cc, ${\mathcal{E}}_{\uparrow }$ =9735, $P_{90\mathrm{\%}}^{\mathrm{FDG}}$=18.2, ${\stackrel{\sim }{\mu }}_3^{\mathrm{FDG}}$ =0.48; (b) TBR_max=1.8, $V_{>70}^{\downarrow }$ =6 cc, ${\mathcal{E}}_{\uparrow }$ =10980, $P_{90\mathrm{\%}}^{\mathrm{FDG}}$ =11.5, ${\stackrel{\sim }{\mu }}_3^{\mathrm{FDG}}$ = 0.17; (c) TBR_max=1.0, $V_{>70}^{\downarrow }$=0 cc, ${\mathcal{E}}_{\uparrow }$ =5702, $P_{90\mathrm{\%}}^{\mathrm{FDG}}$=1.9, ${\stackrel{\sim }{\mu }}_3^{\mathrm{FDG}}$ =0.65. The white contour indicates v_↓, and the dark grey contour indicates v_↑.
