Figure 6.

Scatter plots of fibroglandular volume (V_g) and TBV plotted as a function of (a) age of the participant at the time of breast CT exam; (b) CNL; and, (c) effective diameter of the breast at the chest-wall (D_eff). All the aforementioned parameters exhibited significant correlation with either V_g or TBV (Table 2). (d) The scatter plot of V_g as a function of TBV. While D_eff includes the skin, V_g and TBV exclude the skin and the areolar region. All plots were fitted with a simple power curve.
