Masking is very important when viewing mammograms, especially with high-density breasts. It helps the adaptation of the eye to the luminance of the mammograms on the view box.

The technique of masking allows the comparative study of small areas of both breasts and is a feature of motorised viewers.

Masking should be done horizontal and oblique, both in a cranial and caudal direction, with stepwise movements, to enhance the perception of any subtle, asymmetrical change of breast tissue.
