What is a 3D mammography breast exam?
Tomosynthesis, also called 3D mammography, is a revolutionary screening and diagnostic tool designed for early breast cancer detection that can be done in conjunction with a traditional 2D digital mammogram.
During the 3D part of the exam, the X-ray arm sweeps in a slight arc over your breast, taking multiple breast images. Then, a computer produces a 3D image of your breast tissue in one-millimeter slices, providing greater visibility for the radiologist to see breast detail in a way not possible with 2D mammograms. They can scroll through images of your entire breast like pages of a book.
The additional 3D images make it possible for a radiologist to gain a better understanding of your breast tissue during screening and the confidence to reduce the need for follow-up imaging.
