Figure 2.
Comparison of percentage of breast density from MRI and FFDMs (a) per breast (n = 353) and (b) per study (n = 186).
Each point is labeled with the BI-RADS score. VDG 1, 2, 3 and 4 refer to Volpara Density Grade breast density percentage ranges.

Comparison of breast volume obtained from MRI and FFDMs per (a) breast (n = 353) and (b) per study (n = 186).
Figure 4.
Comparison of fibroglandular tissue volume obtained from MRI and FFDMs (a) per breast (n = 353) and (b) per study (n = 186).
