摘要

In this work, images of exams performed in Digital Breast Tomosynthesis (DBT) system were collected retrospectively from 660 Brazilian women, who underwent screening mammography in clinics located in three Brazilian geographic regions. The raw images were processed using the Volpara software, through which the volume and volumetric density of the breast, the contact area between the breast and the tray, the force and pressure of compression and the thickness of the compressed breast were determined, mean breast size was determined by Volpara, resulting in 737 cm3. The compression force had a median of 79.5 N, with a range of 20 to 160 N and a compression pressure of 9.94 kPa, with a range of 2.6 to 29.5 kPa. The analysis of the correlation between the quantities resulted in percentage dense volume and volume with compression force, r = - 0.259 and r= 0.313, respectively (p < 0.01)), percentage dense volume and volume with compression pressure, r = 0.327 and r = -0.478 (p < 0.01), showing that when it is considered an intrinsic characteristic of the breast there is a greater possibility of standardizing compression through compression pressure instead of compression force.
