Mammography / Breast Imaging

Mammography or mammogram is a type of imaging that uses low-dose X-ray to examine breast tissue. There are two types of mammograms. 

  • Screening mammography is recommended each year to examine breast tissue and check for breast abnormalities.  
  • Diagnostic mammography may be recommended to further examine an area of concern, lump, cyst or follow-up after a screening mammography. 

A new technology called Breast Tomosynthesis or 3-D Mammography can be used in a screening or diagnostic mammography. This new technology allows the radiologist to view the breast in thin "slices" rather than as a whole, which improves the detection of lesions and reduces the need for additional views of the breast.

Yale New Haven Hospital offers online scheduling for mammograms at our Guilford, North Haven and New Haven locations.
