Digital breast tomosynthesis (DBT) has improved cancer screening performance compared with digital mammography (DM), according to a study published online April 11 in Radiology. Christoph I. Lee, M.D., from the University of Washington School of Medicine in Seattle, and colleagues established performance benchmarks for DBT screening in a retrospective study using DBT screening examinations collected from five Breast Cancer Surveillance Consortium (BCSC) registries. Performance measures included abnormal interpretation rate (AIR), cancer detection rate (CDR), sensitivity, specificity, and false-negative rate (FNR), and were compared to concurrent BCSC DM screening examinations. Data were included for 896,101 women undergoing 2,301,766 screening examinations (458,175 DBT and 1,843,591 DM examinations). Source: Advances and More licensed by HealthDay
