Is radiation exposure from 3D mammography higher than regular mammography?

The Food and Drug Administration (FDA) says that 3D mammography must be interpreted along with a conventional 2D mammogram. When first approved in 2011, complying with this requirement meant that women were exposed to twice the radiation dose of conventional mammography. However, two years later the FDA approved a technique that allows imaging software to generate a “synthetic” 2D image from the 3D mammography data. This important breakthrough reduced the radiation exposure to the same low level as a conventional mammogram.
