title: Screen-film mammography versus xeromammography in the detection of breast cancer.
abstract: There are two common methods of obtaining high-quality screening mammography: screen-film mammography (more simply, mammography) using a dedicated unit, and xeromammography. We studied the accuracy of the two techniques in detecting breast cancer by a retrospective study, analysing accuracy of interpretation in cases where both mammography and xeromammography were performed. Seventy-six patients were considered with 86 biopsies and mammograms resulting in detection of 32 cancers and 54 benign lesions. There was no difference in accuracy of interpretation between mammography and xeromammography. The sensitivities were: mammography 0.91, xeromammography 0.88. The specificities were: mammography 0.63, xeromammography 0.75. We conclude that both modalities are comparable in detecting cancer when optimal technique and experienced personnel are used.
