Introductory pictorial atlas of 3D tomosynthesis.

Mammography is an essential tool for early detection of breast cancer. Breast imaging based on three-dimensional digital breast tomosynthesis (DBT) is a new method for breast cancer screening and diagnosis that uses three-dimensional digital images to allow separation of overlapping breast structures, which may allow for improved visualization of potentially significant findings. This article will highlight the utility of DBT as a tool for the detection of breast pathology; it will demonstrate normal findings as well as breast pathology on DBT and two-dimensional conventional mammography. DBT is a very promising modality, which may decrease the false-positive rate of mammography and find additional abnormalities not seen on two-dimensional mammography.
