We compared the interpretative performance of digital versus film-screen mammography in community practice and were reassured to find that no subgroups of women have substantially worse performance with either modality. In fact, digital mammography tended to perform as well or slightly better in most subgroups. Dr. Keen suggests that if we had taken use of computer-aided detection into account, we would have found less favorable performance results for digital compared with film-screen mammography because computer-aided detection is widely used to interpret digital mammograms. Computer-aided detection was more commonly used for digital than for film-screen mammography (56% vs. 23%) in our study. However, this differential use is incorporated in our performance estimates, and despite the more frequent use of computer-aided detection with digital mammography, we found similar performance results for both modalities.
