We developed a 3D modeling analysis to investigate the impact of breast compression on mammographic density. MRI provides 3D information of breast and fibroglandular tissue for creating a 3D model. The volume mesh was created using the ANSYS ICEM CFD software, then the MSC Marc software was used to simulate the breast compression deformation. The results showed that the density variation between 40% to 60% compression level was around 8% on CC view, and 12% on MLO view. The simulation model can be applied to gain more in-depth understanding about the dependence of mammographic density on the potential technical factors.
