(a) and (c) show the Bland–Altman plot between the PD values of the left and right breasts for the proposed algorithm on MLO and CC views, respectively. Similarly, (b) and (d) show the Bland–Altman plots for LIBRA. (e) and (f) show the Bland–Altman plot between the PD estimates of CC and MLO views for the proposed algorithm and LIBRA, respectively. Note that the validation dataset (N = 91 exams, that is, 182 CC and MLO view mammograms) was used for this analysis. Both proposed and LIBRA showed no systematical bias (mean difference < 0.02) between measures, except LIBRA for the PD estimates between the CC and MLO views (mean difference = −0.082), that is, LIBRA overestimated PD estimates of the CC view compared to that of the MLO view. However, LIBRA showed wider variations in PD estimate differences than the proposed algorithm for all comparisons. The proposed algorithm showed high correlation (ρ > 0.87) between left and right PD value estimates for both MLO and CC views, while LIBRA showed only moderate correlation (ρ = 0.66) between left and right PD value estimates for CC views.
