Abstract
The goal of this study was to evaluate the potential of radiation dose reduction in full-field digital mammography (FFDM) compared to screen-film mammography (SFM). An anthropomorphic breast phantom with superimposed microcalcifications (50–200µm) was used to evaluate the detectability of microcalcifications. Images were exposed automatically (AEC mode) using a Mo/Mo anode-filter-combination (protocol A). Dose reduction in digital mammography was achieved by using protocol B with Mo/Rh and protocol C with Rh/Rh. The detectability of microcalcifications was assessed by 3 well- experienced readers with a confidence level ranging from 1 to 5. A receiver operating characteristic (ROC) analysis was performed. Compared to screen- film mammography the digital mammography system allows an equivalent detection rate for microcalcifications at a lower radiation exposure.
