Women’s Imaging: 3D Mammography

What is a mammography?

This test is a significant advancement over the conventional 2D mammogram. Also known as digital breast tomosynthesis, 3D mammograms are up to 40% more accurate than conventional mammograms, with fewer false positives and fewer callbacks.

What are 3D mammograms used for?

Screening mammograms are recommended annually for all women over 40, or younger for those at high risk. This test can find breast cancer early so that more options exist for successful treatment. Diagnostic mammograms are used when there is a suspicious mass within the breast that requires a more detailed evaluation. They are also used to guide treatment and can also measure the effectiveness of treatment.

What should I expect during a 3D mammogram?

Like a conventional mammogram, a 3D mammogram requires light breast compression. While you are standing, the technologist will position your breasts one at a time between two plastic imaging plates within the machine to get optimal images based on your size and shape. Several images will be taken from different positions. The test will take approximately 15 minutes.

How do I prepare for a 3D mammogram?

• You should schedule your mammogram at a time when your breasts are not tender and swollen, like the week just before your period. This can help reduce discomfort and contribute to better quality images. 
• On the day of your test, do not wear deodorant, antiperspirant, lotion or talcum powder under your arms or on your breasts. They may contain substances that can interfere with the images.
• Talk to the technologist about any recent changes in your breasts or any problems that you may be experiencing with your breasts.
• If you had your last mammogram at another center, please bring your previous test results (or have them sent to us) with you to your appointment, if you have them.
