Benefits of 3D mammography:

  • It improves breast cancer detection by up to 40%.
  • It reduces the chance of call-backs for follow-up imaging by up to 40%.
  • It is particularly beneficial for women with dense breasts or with a personal or family history of breast cancer.

What's the difference - 2D vs. 3D?
Image - 3D provides a clearer, more detailed picture of the breast tissue.

  • 2D produces 2 single images of the breast.
  • 3D produces multiple thin images of the breast. This shows greater detail and can uncover cancers hidden in a 2D image by overlapping tissue.

Exam time - Exam time is the same for 2D and 3D.
X-ray exposure - Nearly the same for 2D and 3D.

What is the cost?
Annual screening mammography is a covered benefit under most health insurance plans (including under the Affordable Care Act) and Medicare. Ask your insurance provider about your coverage.
