Data was collected on ESD and AGD from the different CESM studies, and breast density and volume were determined by two expert radiologists. The comparative analysis focused on the dose of radiation received during the craniocaudal (CC) projection of the right breast in CESM studies and FFDM or DBT, performed within a 12-month period.
