Hologic 3D Mammography
Currently, only one product has been approved by the Food and Drug Administration (FDA) for 3D mammography, the Selenia Dimensions digital breast tomosynthesis system manufactured by Hologic, Inc. This system allows a screening exam to include both the traditional 2D mammogram and the new 3D mammogram. There is very little difference in exam time and in the time their breasts are compressed. Very low X-ray energy is used during the screening examination so the radiation exposure is below the FDA limits.
An independent panel of experts appointed by the FDA deemed Hologic’s technology not only safe and effective for breast cancer screening, but clinically superior to conventional 2D mammography (film or digital) alone.1 This is the first significant advance in breast screening technology in decades.
Clinical studies using this system have shown many benefits for the patient:
- Breast cancer screening with 3D mammography finds cancers missed with conventional 2D mammography2
- 3D mammography gives radiologists the confidence to significantly reduce recall rates,3 minimizing the anxiety women feel when asked to return for additional tests
- Breast abnormalities such as masses, distortion, and asymmetric densities are better visualized with 3D mammography4
These demonstrated benefits may help find and fight breast cancer at its earliest stage, when it is most treatable.
Benefits exclusive to the Hologic Selenia Dimensions digital breast tomosynthesis system.
