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)
