Fraction of radiomics features that yielded acceptable consistency (a), discriminative power (b), and repeatability (c) per dose and image reconstruction. Acceptance criteria were an intraclass correlation coefficient (ICC) ≥ 0.75 for consistency, a p value of the Kruskal-Wallis test < 0.05 in ≥ 95% of acquisitions for discriminative power, and an overall concordance coefficient (OCCC) ≥ 0.75 for repeatability. Colored shades accompanying the trend lines indicate 95% confidence intervals
