A demonstration comparing film mammography with the new high sensitivity xeromammography.

The author has performed a subjective comparison of breast images recorded with a new liquid-toner xerographic system and images of the same breasts recorded on Kodak OM-1 film exposed with a MinR screen and a 5 to 1 grid. The xeromammograms are judged to be superior to the mammograms recorded on film with respect to: (1) the demonstration of calcifications, circumscribed masses, and the back of the breast; (2) the "resolution" of dense connective tissue; and (3) the overall image quality. Radiation doses to the breast associated with the two types of study are said to be comparable. Thirteen pairs of excellent images comparing xeromammograms with conventional breast films are presented.
