• 3-D Mammography

    3-D mammography (breast tomosynthesis), is a screening tool designed for early breast cancer detection. It can be used along with traditional 2-D mammography as a part of your annual screening to capture additional breast images. The technology also provides clearer images that allows doctors to examine breast tissue one layer at a time and find otherwise hidden cancers.

    What is the difference between 2-D and 3-D mammography?

    3-D mammography complements standard 2-D mammography and is performed with the same system.

    With traditional 2-D mammography, the scan of your breast tissue is viewed in one flat image. Sometimes breast tissue can overlap, giving the illusion of normal breast tissue looking like an abnormal area, which could result in the need for additional testing.

    With 3-D mammography the breast tissue is scanned in one millimeter slices, allowing the radiologist to view a clearer image of the breast tissue.

    What are the benefits?

    3-D mammography provides greater visibility of the breast details for the radiologist. This allows the radiologist to give a more confident reading, and help eliminate the need for additional appointments.

    3-D mammography is also known to find cancers missed with conventional 2-D mammography.

    What should I expect during the 3-D mammography exam?

    Your 3-D mammogram will be performed at the same time as your 2-D mammogram. No additional compression is required, and it will only take a few seconds longer to properly capture each view.

    During the 3-D part of the exam, the X-ray arm sweeps in a slight arc over your breast, taking multiple breast images.

    The exam will take approximately 15 minutes.

    Who can have a 3-D mammography exam?

    3-D mammograms are approved for all women who are eligible for a standard mammogram.

    Is there more radiation exposure?

    Very low X-ray energy is used during the exam, and your radiation exposure will remain safely below the American College of Radiology (ACR) guidelines.

    Where can I receive a 3-D mammogram?

    We offer 3-D mammograms at Lahey Outpatient Center, Lexington, Lahey Medical Center, Peabody and Lahey Hospital & Medical Center, Burlington.
