Tomosynthesis recall rate decreases sustained over time!

Digital breast tomosynthesis (DBT) has been shown to reduce recall rates and increase cancer detection in screening when compared with digital mammography.

Researchers led by Dr. Christine Chen from Yale University reviewed DBT exams performed over four consecutive years (August 2011 to July 2015). They analyzed the recall rate, cancer detection rate, and positive predictive value for recall (PPV1) for each one-year period and compared the results with those from a control group of digital mammography exams taken between August 2008 and July 2010.

“The sustainable, superior performance of DBT over [digital mammography] illustrates the integral role of DBT in breast cancer screening, which has important implications for policymaking in the future,” she concluded.
