Digital breast tomosynthesis can detect cancer at a higher rate than digital mammography, according to a study published Sept. 17 in Radiology.
Researchers from New Haven, Conn.-based Yale School of Medicine analyzed 272,938 breast cancer screening results at Yale University and Yale-New Haven Health from August 2008 through July 2021. The findings were interpreted by 15 breast radiologists, the study said.
Digital breast tomosynthesis had a higher rate of cancer depiction (5.3 cancers per 1,000) compared to digital mammography (four cancers per 1,000), out of the 1,407 breast cancer cases analyzed.
Fewer cancers were in advanced stages at the time of diagnosis when digital breast tomosynthesis was used (32.7%) compared to digital mammography (43.6%).
