Tomosynthesis in Screening Mammography

We will evaluate the effect of tomosynthesis mammography outcomes in a screening setting. We will collect data on interpretation time, recall rates, cancer detection rates, and interval cancer rates in dense breasts(≥ 50% glandular density). If the interpretation time is less than 4X a routine read, and the recall rates have dropped \< 30% of initial values, we will then conduct a study with larger numbers to better evaluate cancer detection rates and interval cancer rates.
