3D Mammography

There is no disagreement that early and accurate diagnosis of breast cancer is the key to a good outcome. When detected early, the five-year survival rate is 98 percent.

Currently, 2D digital mammography is considered the standard of care for detecting breast cancer early, sometimes even before a physical change is noticed. Woman’s Hospital now has the technology to potentially detect cancer even sooner with 3D mammography.


Performing more than 45,000 mammograms a year, Woman’s is the regional mammography leader and is committed to providing women with the most advanced tools – such as 3D mammography – and education in detecting breast abnormalities. 


What is a 3D mammogram

3D mammography is a blend of current and new mammogram technology. This new technology, called breast tomosynthesis, involves the acquisition of more than 120 one-millimeter thin, 2D images of each breast. These images are then layered or “sliced” to create a three-dimensional view of the breast tissue.

Why choose a 3D mammogram

3D mammography produces clear, precise images that allow doctors to pinpoint the location of abnormalities with greater accuracy. The 3D mammogram may also find cancers that hide in dense breast tissue, resulting in fewer false negative studies. The frequency of callbacks from routine screening mammograms is reduced when combined with 3D, thus decreasing patient anxiety. As with standard digital mammography, the radiation exposure remains low, and the increased time to perform a 3D mammogram is minimal.

Additionally, at Woman’s, all breast imaging studies are read by a board-certified radiologist and a Computer-Aided Detection System to ensure the highest accuracy possible. Woman’s is the only hospital in the Baton Rouge region that has two radiologists reading each breast imaging study. In 2013, more than 250 breast cancers were diagnosed at Woman’s; 5 percent were identified during the second reading of the mammogram.

Who should consider a 3D mammogram

Woman’s strongly believes in 2D technology, monthly breast self exams and annual exams by healthcare providers for detecting breast changes. 3D mammography may be beneficial for women with a personal history or high risk of breast cancer, and for women with dense breast tissue.

In addition to mammography, Woman’s provides comprehensive breast imaging and breast cancer treatment, including a dedicated breast cancer patient navigator, who works with patients to improve access to cancer treatment by coordinating appointments, reviewing paper work and facilitating physician-patient communication.
