Imaging findings OR Procedure details
2240 mammography images from 527 women acquired by two GE digital systems (a Senographe DS and a Senographe Essential) were processed by Volpara.
Patient age distribution was between 32 and 86 years,
median 51 y (Figure 7).
Breast thickness values were normally distributed (Figure 8) while breast volume and breast density showed log-normal distribution (Figures 9 and 10).
It can be noticed that all the analyzed breasts showed density value below 50%,
for long time considered the “typical value” for most breasts [7].
Breast density distribution analysis indicates that 85% of breasts had volumetric density below 20%,
and 95% of them had volumetric density below 30%.
That matches with recent results from Yaffe,
Boone et al [8] looking at breast CT judged density.
The expected decreasing trend of breast density versus patient age was confirmed by the quantitative analysis (Figure 11).
Finally,
the correlations between left and right breasts,
and between CC and MLO views were high,
as depicted by Figures 12 and 13.
