Radiation dose with digital breast tomosynthesis compared to digital mammography: per-view analysis.
Type
ArticleAbstract
The objective of this study was to compare radiation dose delivered by digital mammography (FFDM) and breast tomosynthesis (DBT) for a single view.
4,780 FFDM and 4,798 DBT images from 1,208 women enrolled in a screening trial were used to ground dose comparison. Raw images were processed by an automatic software to determine volumetric breast density (VBD) and were used together with exposure data to compute the mean glandular dose (MGD) according to Dance’s model. DBT and FFDM were compared in terms of operation of the automatic exposure control (AEC) and MGD level.The objective of this study was to compare radiation dose delivered by digital mammography (FFDM) and breast tomosynthesis (DBT) for a single view.
