Digital breast tomosynthesis (DBT) improves cancer detection rates when the technology is used in an organized breast cancer screening program, according to researchers from Norway.

In this Monday morning presentation, Dr. Per Skaane, PhD, from Oslo University Hospital will outline research that analyzed cancer detection rates before, during, and after DBT was implemented at the hospital, using data from the years 2007, 2009, 2011, and 2013.

Adding DBT to mammography improved the cancer detection rate, the team found. The detection rate rose from 4.7 cancers per 1,000 exams in 2009 to 9.7 cancers per 1,000 exams in 2011. The interval cancer detection rate remained stable.

The findings demonstrate that using DBT with mammography finds more cancers, while interval cancer detection rates could use further study, Skaane's group concluded.
