3D Mammography

Also known as tomosynthesis, 3D mammography is a major leap forward in breast screening technology. It offers up to 40% improved detection with fewer call-backs and fewer false positives.

Unlike traditional 2D mammography, it has specially designed digital detectors that capture multiple segments or ‘slices’ of the breast at different angles. A computer then restructures these slices into a three-dimensional image that can be displayed in high resolution. A 3D mammogram can find cancers that a 2D mammogram can miss, especially in women with dense breast tissue.

Screening vs. Diagnostic Mammograms

Screening mammography is recommended for all women starting at age 40, or younger if you are at higher risk. It is a preventive imaging test designed to detect breast cancer at its earliest stages. You should have this test every year.

If an abnormality is found on a screening mammogram, or if you have symptoms, your doctor may order a diagnostic mammogram. This is a more detailed test to confirm—or rule out—breast cancer. It is important to know that the majority of abnormalities are NOT cancer.

Preparation Instructions

No special preparation is required for a screening mammogram. However, please let us know:

• The date of your last menstrual period
• If you are pregnant or may be pregnant
• If you are post-menopausal
• If you are receiving hormone therapy or taking oral contraceptives
• If you are having fertility treatments or taking fertility medication
• If you are currently breastfeeding

If you are having a diagnostic mammogram, we will notify you in advance of any preparation instructions.

What to Expect

Having a 3D mammogram is just like having a 2D mammogram. During your mammogram, a specially trained radiologic technologist will position you to image your breast. Your breast is placed on a platform and compressed gently, and images will be taken of both breasts. 

A screening mammogram typically takes 30 minutes or less and you can resume normal activities immediately following your exam. The images will be interpreted by a board-certified radiologist and a report will be sent to both you and your doctor. If your mammogram reveals that you have dense breast tissue, you will be notified as this could increase your risk for breast cancer.
