DBT (Digital Breast Tomosymthesis) mammography finds more cancers — dense tissue or not
April 26, 2016 — Studies suggest that digital breast tomosynthesis (DBT) not only improves cancer detection rates, it also decreases recall rates, especially in women with dense breast tissue. But it’s also beneficial for women who don’t have dense tissue, according to research published in the April 26 issue of the Journal of the American Medical Association
When combined with digital mammography, DBT decreased recall rates 14% and improved cancer detection rates 48% in women with dense tissue. In addition, in women with fatty breast tissue, the recall rate was 12% lower and the cancer detection rate was 30% higher.
“The message in our data is that whether a woman has dense tissue or not, tomosynthesis is beneficial,” said lead author Dr. Elizabeth Rafferty of L&M Radiology in West Acton, MA. “We’re used to incremental gains when a new technology is introduced, but these results are beyond incremental.”
