15_stv_wc_7069-199x300Three-dimensional (3D) mammography, also known as breast tomosynthesis, is a type of digital mammography in which X-ray machines are used to take pictures of thin slices of the breast from different angles and computer software is used to reconstruct an image. This process is similar to how a computed tomography (CT) scanner produces images of structures inside of the body. Conventional digital mammography produces one image of overlapping tissue, making it difficult to detect cancers. Performed with digital mammography using the same scanner, breast tomosynthesis takes multiple images of the entire breast. It allows our specialized breast radiologists to see through layers of tissue and examine areas of concern from all angles.


  • Earlier detection of small breast cancers that may be hidden during digital mammography
  • Greater accuracy in pinpointing size, shape and location of abnormalities
  • Greater likelihood of detecting multiple breast tumors, which occur in 15 percent of breast cancer patients
  • Clearer images of dense breast tissue

Tomosynthesis is beneficial for the high-risk breast patient and those with very dense breast tissue. There may be additional fees for the radiologist to review this specialized imaging.
