Liver Morphomic feature definitions found in Figure 2
| Feature name | Definition |
| decile4_3dauto | Density in hounsfield units (HU) within the liver volume was binned into 11 groups, ranging from −250 to 300 HU and decile 4 is the fourth group |
| pvlenratio_3dauto | Ratio between portal vein tip length and cross-sectional length (y axis) of the liver |
| osnldistratio_3dauto | Total smoothed perimeter divided by the total original perimeter using the 3D liver surface nodularity (OSNL) surface path |
| equivdiameter_3dauto | Equivalent diameter (in mm) derived from the surface area of the liver |
| osnl3dquartile2_3dauto | Liver surface nodularity 2D measures were binned into 4 groups. This is the aggregate measure (in mm) from the second group. |
| xlenmm_3dauto | Length of the x axis of the liver (in mm) |
| eccentricity3d_3dauto | Major axis length divided by minor axis of the liver volume |
| pv2tiplen_mm_3dauto | Distance from portal vein bifurcation point to the leftmost edge of the visualized liver (in mm) |
