Study findings1 published online August 13, 2019 in Radiology concluded: “Digital breast tomosynthesis enabled the detection of more cancers in all density and age groups compared with digital mammography, especially cancers classified as spiculated masses and architectural distortions. The improvement in cancer detection rate showed a positive correlation with age. With use of digital breast tomosynthesis, false-positive findings were lower due to fewer asymmetric densities, except in extremely dense breasts.” The study abstract can be accessed here (subscription required for full text).
An accompanying editorial, Can Digital Breast Tomosynthesis Solve the Challenge of Dense Breast Parenchyma? was authored by Drs. Fuchsjäger and Adelsmayr, from the University of Graz, Austria. Dr. Fuchsjäger also serves as the DB-I/Europe Education Ambassador for Austria.
While this study provides further confirmation of the benefit of 3D mammography in screening dense breasts, DB-I’s FAQ #30 for health care professionals addresses the question of whether there is a benefit to screening ultrasound after 3D mammography (Hint – there is).
