Effectiveness of Digital Breast Tomosynthesis Compared with Digital Mammography

In this article, the research team looked to determine whether improved initial outcomes of using DBT could be sustained over time.  The study was completed over 4 years and included 44,468 screenings attributable to 23,958 women.  The research team looked to compared recall rates, cancer cases per recalled patients, and biopsy and interval cancer rates.  Each women was followed over the course of 4 years and received either 1, 2, or 3 DBT screenings.  The number of screenings were then used as an intervention to determine the patient’s health.

The results of the study showed that the use of DBT remained significantly reduced compared with using digital mammography alone.  Overall, the study found that digital breast tonosynthesis outcomes are not only sustainable but provide significant recall reduction and a decline in interval cancers.
