The purpose of this study is to compare the visibility of microcalcifications of digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) using breast specimens.
Thirty-one specimens' DBT and FFDM were retrospectively reviewed by four readers.
The image quality of microcalcifications of DBT was rated as superior or equivalent in 71.0% by reader 1, 67.8% by reader 2, 64.5% by reader 3, and 80.6% by reader 4. The Fleiss kappa statistic for agreement among readers was 0.31.
We suggest that image quality of DBT appears to be comparable with or better than FFDM in terms of revealing microcalcifications.
本研究的目的是使用乳腺标本比较数字乳腺断层合成（DBT）和全视野数字乳腺摄影（FFDM）中微钙化的可视性。
四位阅片者对31个标本的DBT和FFDM进行回顾性分析。
阅片者1将DBT微钙化的图像质量评为优于或等同于FFDM的比例为71.0%，阅片者2为67.8%，阅片者3为64.5%，阅片者4为80.6%。阅片者之间一致性的Fleiss卡方统计值为0.31。
我们认为，在显示微钙化方面，DBT的图像质量似乎与FFDM相当或更好。
