Mammogram - Screening/Diagnostic/3D/Tomosynthesis

Mammograms, 3D mammography in St. Louis


A mammogram is a specific type of imaging that uses a low-dose x-ray system to examine breasts.  A mammogram is used to aid in the early detection and diagnosis of breast disease in women.  An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.  Imaging with x-rays involves exposing a part of the body to a small dose of radiation to produce pictures of the inside of the body.  X-rays are the oldest and most frequently used form of medical imaging.  Three recent advances in mammography include digital mammography, computer-aided detection and breast tomosynthesis, all of which are available at Mallinckrodt Institute of Radiology.
