Breast Sonography and Mammography: Complementarity and Correlation.

Mammography is a proven tool for detecting breast cancer and reducing breast cancer mortality, but breast sonography plays an important role in promoting breast health, too. These modalities can complement each other, especially when images are correlated to examine an abnormality or suspicious area. This article discusses how breast sonography supplements mammography as a screening and diagnostic technique, how mammographic and sonographic images are correlated, and how some common breast diseases and conditions appear on the 2 modalities. The limitations of both breast imaging modalities also are discussed.
