简要总结
The purpose of this image acquisition study is to compare, in a Reader Study, the RI8 system used in conjunction with a conventional mammography to mammography alone, and to determine whether the addition of supplementary RI8 result will improve ROC area under the curve. The study is prospective, multi-center, sequential, control trial with the woman serving as her own control. Women determined to have heterogeneously or extremely dense breast based on her previous mammogram and are undergoing routine screening mammography at one of the clinical sites assigned for this study will be eligible to join the study.

- •B. Subjects who are asymptomatic and scheduled to undergo routine screening mammography.
- •C. Subjects scheduled for image-guided needle biopsy as a result of findings obtained during standard of care imaging modalities (mammography, ultrasound and/or MRI) performed at the clinical site that participates in the study.
