In community-based radiology practice, mammography screening with 3D digital breast tomosynthesis (DBT) yielded an increased overall cancer detection rate, lower recall rates and an increased detection rate for invasive cancer compared with 2D digital mammography (DM).
In the largest report to date, researchers at Washington Radiology Associates, PC, with offices in Washington, DC; Virginia; and Maryland, conducted a study of more than 59,000 patients. The results were striking: an increase in the detection rate for cancer overall of 28.6% and a 43.8% increase in detecting invasive cancers in patients screened with 3D DBT versus 2D DM.

"Our results may be a bellwether for the impact of tomosynthesis on population-based breast cancer screening."
The study appears ahead of print online in the American Journal of Roentgenology.
