We have developed a stereoscopic mammography system using state-of-the-art digital technology that enables a mammographer to view the internal structure of the breast directly in depth. The primary aims of this project are to further develop and refine this system and then to evaluate its effectiveness in increasing the accuracy of diagnosis of breast cancer relative to the diagnostic accuracy afforded by standard, non-stereo film views. The expected increase in diagnostic accuracy could increase the yield of biopsy substantially by allowing the radiologist to more confidently recommend accelerated follow-up of truly benign disease and biopsy of truly malignant disease. Our accomplishments in Year 1 consist of progress in three areas 1 improvements made to the stereo display workstation, 2 installation and testing at UMMC of a new GE full-field-of-view digital mammography unit, and its first use in acquiring stereo mammograms from several patients prior to biopsy, and 3 work on identification of visual features of lesions and normal breast tissue which can be seen uniquely, or better, in depth.
