3D Mammography Creates More Precise Images to Detect Breast Cancer

When it's time for a mammogram, should you ask for 3D?

When Mary Hu, an administrator in communications with Yale School of Medicine, went to get a mammogram two years ago, she didn't even know she was getting 3D mammography, also called digital breast tomosynthesis. Her radiologist, Dr. Liane Philpotts, with Yale Cancer Center, says Hus experience is a great example of the accuracy of 3D imaging. Hu has dense breasts, which can make it challenging for radiologists to read mammograms since the breast tissue can mask worrisome tumors.

With 3D mammography, doctors are able to see through breast tissue better than they can with 2D and are therefore more likely to discover tumors that may be hiding in dense tissue. Like traditional mammograms, 3D requires immobilizing the breast and compressing such that there is no motion and such that we get fine detail. Two studies have found that women who have 3D mammograms are less likely to be called back for further testing such as a follow-up mammogram or ultrasound.
