  • 3-D Mammography

  • Martha Mainiero, MD, director of the Anne C. Pappas Center for Breast Imaging, explains digital breast tomosynthesis, or 3D mammography, which allows radiologists to see deeper and more detailed images than typical mammograms.

    Digital Breast Tomosynthesis

    The Anne C. Pappas Center at Rhode Island Hospital now offers patients one of the most significant advancements in breast imaging: digital breast tomosynthesis.

    Tomosynthesis is a new type of digital mammogram that provides three-dimensional (3-D) images of the breast, which provides the radiologist with significantly more visual information about the mammogram.

    With a standard two-dimensional (2-D) mammogram, overlapping tissue can hide abnormalities or can make normal tissue appear suspicious. As a result, some women need to return for additional images to be taken.

    Tomosynthesis, however, gives the radiologist a way to see the whole breast in 3-D without the uncertainty caused by overlapping tissue or normal variation in breast tissue. This offers improved ability to confirm that tissue is normal, reduces the need for additional imaging and spares our patients any additional inconvenience or concern.

    Patient Experience

    The 3-D mammogram takes only a few seconds longer to obtain images, and is done with the breast positioned in the standard fashion, so the mammography experience does not seem very different.

    Tomosynthesis is FDA-approved and the radiation exposure is within the limits for standard 2-D digital mammography.
