The 3-D mammogram (or breast tomosynthesis) is a revolutionary, FDA-approved digital technology that enables doctors to find smaller tumors sooner for earlier detection of breast cancer. This 3-D imaging technology allows radiologists to see inside the breast, reducing or eliminating problems caused by overlapping tissue.

What to Expect from a 3-D Mammography Exam
3-D mammography does not replace traditional 2-D mammography. It is performed at the same time and uses the same scanner as a conventional mammogram. During the 3-D part of the exam, an x-ray arm sweeps over the breast, taking a series of images at a variety of angles. These images are displayed as a series of thin slices that radiologists can view as individual images or in an interactive animation. The whole procedure should take approximately the same amount of time as that of a conventional mammogram. 

3-D Mammography Benefits
There are several benefits to 3-D mammograms:
  • Earlier detection: 3-D mammography provides multiple images that can be taken apart and examined individually. This may help detect smaller tumors earlier than conventional mammography.
  • Better visualization: 3-D mammography allows radiologists a better view of the location, size and shape of an abnormality. 
  • Fewer callbacks: 3-D mammograms can help radiologists distinguish harmless abnormalities from real tumors, meaning fewer callbacks for additional images and less anxiety for women.
