BID-Milton Now Offering Three-Dimensional Mammography

Beth Israel Deaconess Hospital – Milton recently installed a new three-dimensional (3-D) mammography system and is now providing this state-of-the-art imaging technology which has been shown to increase breast cancer detection rates in women by up to 40%.

The hospital’s new Hologic Genius® 3-D mammography system has been proven by numerous clinical studies to provide significant benefits compared to two-dimensional mammography. In addition to a 40% improvement in breast cancer detection rates, particularly in women with dense breast tissue, 3-D mammography also reduces “false positive” results and “call backs” for repeat mammograms by 20%.

The difference between traditional two-dimensional mammography and 3-D mammography lies in the number of images taken of the breasts and how they are displayed to radiologists interpreting the mammogram results. Two-dimensional mammography only takes images of the breasts from two angles. Because the images are compressed, suspicious areas can be hidden between layers of breast tissue, a problem in particular for women with dense breast tissue.

With 3-D mammography, multiple three-dimensional images are taken of the breast and displayed layer-by-layer. As a result, suspicious areas are less likely to be hidden by tissue above or below and are easier for the radiologist to identify.

“Woman may not notice a difference in how the 3-D exam is performed compared to the traditional two-dimensional exam but the benefits of this new technology are significant. 3-D mammography offers improved clarity and breast cancer detection,” explained Brook Longmaid, MD, chief of radiology at BID-Milton and a member of Harvard Faculty Physicians at Beth Israel Deaconess Medical Center. “This state-of-the-art system also offers patients greater peace of mind, which is invaluable.”

The new 3-D mammography system is the latest addition to BID-Milton’s growing Women’s Health Program. Last fall, the hospital began offering, for the first time, minimally invasive robotic surgery for pelvic prolapse and certain cervical and endometrial cancers.
