Sensitivity of radiomic features to noise. (a) Average percent change (APC) of radiomic features as a function of noise. The X- axis corresponds to added noise level [α₁ ≈ 33(SNR); α₂ ≈32(SNR); α₃ ≈28(SNR); α₄ ≈23(SNR); α₅ ≈17(SNR); α₆ ≈11(SNR)], and Y-axis corresponds to the radiomic features (1- 48)(see Supplemental table S#) . (b) and (c) depict the proportion of radiomic features at different bias with increasing noise for 2D and 3D analyses, respectively. The bias is denoted by the colour-scale legend below panel C.
