3D Tomosynthesis Mammography
What is a 3D Mammogram?
3D mammography, also known as Digital Breast Tomosynthesis. A 3D mammogram is performed in the same way as a conventional 2D; however, the x-ray arm sweeps in a small arc over the breast, taking multiple images. This allows the Radiologist to examine your breast tissue layer by layer, making it easier to see fine details and abnormalities that may be hidden by overlapping tissue on a 2D mammogram.
What should I expect during a 3D mammogram?
The process is the same as a routine digital screening mammogram (2D).
The technologist will position you and compress your breast tissue, taking images from different angles. It will take a few seconds longer to get each image because the x-ray arm will move in a slight arc over the breast, obtaining many images at once. 3D mammography does not feel different from a conventional mammogram.
Do I need a 3D mammogram?
This is a decision that should be made between you and your doctor. 3D mammography has been shown to benefit women with dense breasts in particular, but many studies are showing there are benefits for women with breasts of any density.
Is it more radiation than 2D?
There is a small increase of radiation from a conventional digital mammogram but it is still well under the FDA limit for recommended dose levels.
Will my insurance cover 3D mammography?
Each insurance plan varies. Even though many are now paying for 3D, it is important to call and ask about your specific plan.
