Figure 3

Test–retest repeatability of radiomic features. Bar plots demonstrate the percentage of repeatable features (concordance correlation coefficient (CCC) ≥ 0.9 and dynamic range (DR) ≥ 0.9) for individual VMI energies (40 to 190 keV), DECT approaches (SFDE = split-filter dual-energy, DSDE = dual-source dual-energy), and radiation doses (5, 15 mGy). Overall, DSDE demonstrated higher repeatability at higher radiation dose (light green) and less variability among VMI energies compared to SFDE (blue).
