3D mammography (breast tomosynthesis), is a screening tool designed for early breast cancer detection. It can be used along with traditional 2D 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.
3D mammography complements standard 2D mammography and is performed with the same system.With traditional 2D 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 3D mammography the breast tissue is scanned in one millimeter slices, allowing the radiologist to view a clearer image of the breast tissue.
3D 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.3D mammography is also known to find cancers missed with conventional 2D mammography.
Your 3D mammogram will be performed at the same time as your 2D mammogram. No additional compression is required, and it will only take a few seconds longer to properly capture each view.During the 3D 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.
3D mammograms are approved for all women who are eligible for a standard mammogram.
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.
We are now offering 3D mammograms at Lahey Outpatient Center, Lexington and Lahey Medical Center, Peabody. We will offer 3D mammogaphy at Lahey Hospital & Medical Center, Burlington, in February.
