Compression in mammography

In mammography, compression of the breast is performed to reduce its thickness. By doing so, the following benefits are achieved:

  • improved subject contrast (by reducing scattered radiation)
  • improved density uniformity
  • improved visualization of breast tissue near chest wall (by spreading out superimposed anatomy
  • decreased radiation dose
  • decreased blurring (by reducing motion artefact)

Compression is performed by the use of compression paddles, a component of the mammographic unit, which can vary in size and function.

The typical compression force used in mammography is between 10 and 20 Newtons.
