In 2D mammography, two X-ray images are taken, one from the top, and a second from the side. In 3D mammography, take multiple pictures of each breast from different angles.
3D mammography is becoming the standard of care within hospitals, imaging centers, and physician’s offices. 3D mammography has been FDA-approved in the US since 2011. Starting around 2015 more and more insurance companies now pay for these 3D scans because studies show 3D mammography is more accurate than traditional mammography in the early detection of breast cancer.
