Abstract : Work to optimize the appearance of digitized film mammography and digital mammography using storage phosphor technology is nearly complete. The attached report and its appendices indicate that digitized film mammography (digitized at 100 micron pixel size) is insufficient for clinical interpretation with soft copy display. Hard copy display is still insufficient, however, we are planning tests of a newer method for hard copy display during the coming (final) year of the project. Digital mammography using storage phosphor methods has been optimized and an ROC analysis of this method using our current data set of approximately 30 proven cancer cases and a matched number of benign cases is about to begin. This ROC study will compare matched conventional and digital images using six radiologists. Each of the cancer and benign finding cases is pathologically proven. We are also exploring special image processing methods for the radiodense breast and these are discussed in this report.
