What is the difference between a traditional mammogram and a 3D mammogram?

Digital mammography uses a specially designed digital camera and a computer to produce an image that is displayed on a high-resolution computer monitor. Although an adequate breast cancer screening tool, digital mammography produces only a 2-dimensional picture of the breast. Traditional mammograms take only one picture, across the entire breast, in two directions: top to bottom and side to side – flattened images.

With 3D mammography or digital breast tomosynthesis multiple pictures are collected and reconstructed into thin slices of breast tissue. Breast tomosynthesis uses high-powered computing to convert digital breast images into a stack of very thin layers or “slices’ – building what is essentially a “3-dimensional mammogram”. This technology makes it possible for the radiologist to see breast tissue detail in a way never before possible.

Instead of viewing all the complexities of breast tissue in a flat image, the doctor can examine the tissue a millimeter at a time. It is similar to being able to read each page of a book rather than trying to peer through all the pages at once. The radiation dose for 3D mammography is equal to that of conventional mammograms.
