3-D Imaging Improves Breast Cancer Detection

For decades, two-dimensional mammography X-rays defined the way in which  physicians detected abnormal legions in breast tissue. Now, a new  technology called stereoscopic digital mammography (SDM) holds  significant promise to not only make earlier detection of cancer cells  possible, but to help radiologists and doctors see legions that would  otherwise be masked.

The usefulness of SDM  technology lies in its ability to provide doctors with 3-D images that  duplicate the natural ways in which the human eye can see. The benefits  of such imaging are two-fold: the technique increases accuracy and early detection, and it decreases the number of false positives, saving many  women from being called back for follow-up testing, as well as the fear  and worry that often accompanies those procedures, including ultrasound  testing and tissue biopsy.

“Our eyes see the world from two slightly different perspectives,” says Carl J. D’Orsi, M.D., head of the Department of Radiology and Imaging  Sciences at Emory University in Atlanta, one of a few places in the  United States where SDM technology is already in place and where  research that compared both types of imaging was conducted.
