Simulated Screening Study of Combined Digital X-Ray, Ultrasound and Photoacoustic Breast Imaging

This is a pilot, simulated breast cancer screening study. In a population enriched with mammographic call-backs, we will study whether: 1) Combined digital breast tomosynthesis(DBT)/dual-sides 3 dimensional-automated ultrasound(AUS)will result in a lower call-back rate than digital breast tomosynthesis(DBT)alone. 2. Explore the utility of photoacoustic imaging as an adjunct to digital breast tomosynthesis(DBT)/ultrasound(US)alone. This study will compare two new breast imaging systems to digital mammography and hand-held ultrasound that are commonly used to find and evaluate breast masses. Images will be done with digital breast tomosynthesis (DBT) and 3-D automated ultrasound(AUS) which will be done in the breast imaging clinic of the main hospital followed by the second light and ultrasound imaging that will be completed in the research lab.
