Assessment of Digital Breast Tomosynthesis (DBT) in the Screening Environment

The objective of this study is to demonstrate that digital breast tomosynthesis (DBT) in combination with full field digital mammography (FFDM) has the potential to reduce significantly baseline screening recall rates without a loss in the detection of cancers. The primary hypothesis of the study is that DBT in combination with FFDM will reduce baseline screening mammography recall rates in negative examinations by at least 20%.

Primary Outcome Measures:
  • Number of Participants Without Cancer Who Were Recalled [ Time Frame: upon recruitment/enrollment phase completion ]
    Recall rates of digital breast tomosynthesis and full field digital mammography in younger women undergoing their initial screening mammogram will be assessed and compared.

Enrollment: 1080
Study Start Date: May 2010
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: tomosynthesis and screening mammography
    All eligible subjects will undergo both full field digital mammography and digital breast tomosynthesis.
    Other Name: digital breast tomosynthesis
Detailed Description:
The FFDM images and the FFDM images with the DBT images will be interpreted independently by two experienced radiologists under standard clinical screening procedures. Recommended recall rates will be assessed and compared as a result of each of the two interpretations.
