3D Mammography May Be Better

Finds more cancers than regular digital.

Pennsylvania researchers say just like some movies, mammograms are better when they're 3D. A new study finds that 3D mammography is better at finding breast cancer than conventional digital mammography.

Researchers at the University of Pennsylvania compared imaging results from more than 15,000 women who underwent 3D mammography to those of about 11,000 who had digital mammograms.

They say the 3D tests found 22 percent more breast cancers and led to fewer call backs. Study authors say the 3D method, called tomosynthesis allows for 3D reconstruction of the breast tissue, giving radiologists a clearer view of overlapping tissue.
