| Abstract:: |
| Objective To describe the distribution of volumetric breast density(VBD) in different ages of Chinese women based on X-ray mammograms.Methods Based on mammographic images of 1 140 patients from January 2010 to December 2016 in a hospital in Beijing, the VBD of women was assessed by Volpara 1.5.1 and graded according to breast imaging reporting and data system published by American College of Radiology. The patients were divided into two groups according to the median age, and the two independent samples t-test was used to compare them. The patients were also divided into four groups according to age ( <40 years, 40-49 years, 50-59 years, ≥ 60 years), and the breast thickness, breast volume, glandular volume, and VBD were compared using a One-way ANOVA analysis.Results The median age was 50 years. The compressed breast thickness and breast volume in patients over 50 years were significantly higher than those in patients below 50 years (t= -8.99, -7.92, P<0.001), while glandular volume and VBD were significantly lower than those below 50 years (t= 8.11, 18.49, P<0.001). The compressed breast thickness, breast volume, glandular volume, and VBD were statistically significant different among four groups (F=27.10, 22.34, 25.70, 122.03, P<0.001). Patients over 60 years had the lowest VBD (t=-12.56, -15.27, -4.57, P<0.001). VBD was negatively correlated with ages (r=0.47, P<0.001).Conclusions The compressed breast thickness and breast volume increased with ages, while the glandular volume and VBD decreased with ages. |
