Does Breast Imaging Experience During Residency Translate Into Improved Initial Performance in Digital Breast Tomosynthesis?

A randomized controlled trial of digital breast tomosynthesis versus digital mammography in population-based screening in Bergen: interim analysis of performance indicators from the To-Be trial

“…Results from other studies indicate the need for training and workshops before reading DBT in screening [30, 31]. In our study, the radiologists’ experience in DM screen reading before the trial period varied from beginners to very experienced, the latter with more than 100,000 screen reads during their career as a breast radiologist.…”

“…A limitation of this study is the short time spent on training and workshops in DBT for radiographers before the start of the trial, which could have influenced the results in either direction [30, 31]. Moreover, we have not presented breast cancer detection data; this decision was based on per protocol power estimation, which showed that 2 years of screening—one screening round—was needed to show a 25–30% difference in the rate of screen-detected breast cancer between DBT and DM.…”
