New technology offers the next generation of mammography
Date:10/1/2011

offered the system. UH uses the Selenia Dimensions 3D digital mammography system, manufactured by Hologic and recently approved by the FDA, combining advanced digital mammography and tomosynthesis-generated images to provide a more detailed, highly focused picture of the breast.

The system acquires multiple, low-dose images at different angles, similar to Computed Tomography (CT) of the body. These images are then used to produce a series of one-millimeter thick slices that can be viewed as a 3D reconstruction of the breast. Women getting a mammogram will not feel any difference on the new machines. The tomosynthesis unit looks similar to the previous mammogram machines and the amount of breast compression is identical to the conventional mammogram.

The technology gives radiologists the ability to identify and characterize individual breast structures and clearly see features which might be obscured in a traditional two-dimensional mammogram by overlapping normal breast anatomy that may mimic or mask a tumor. Dense tissue and overlapping tissue structures may lead to false positive or false negative results with standard mammography.

Tomosynthesis additionally has the potential to decrease the number of women who need to return for additional testing. Nationally, about 10 percent of women who undergo a regular screening mammogram are recalled for additional mammogram images after an abnormality is detected which can be very stressful.

"This cutting edge technology helps radiologists detect, screen and find breast cancers at very early stage tumors when they're small," adds Dr. Plecha. "It also helps us to pinpoint the location, size and shape of the cancer. Our only and best defense against breast cancer is catching it early and curing it at a more treatable stage and tomosynthesis provides us with an important new tool to decrease cancer mortality and save lives."
