Haider I, et al. - In this institutional review board–approved, retrospective, multireader study, the researchers assessed the perceptual difference in breast density classification using synthesized mammography (SM) compared with standard or full-field digital mammography (FFDM) for screening. From June 1, 2016, through November 30, 2016, they assessed breast density on 200 patients who underwent baseline screening mammogram during which both SM and FFDM were obtained contemporaneously. It was observed that overall subjective breast density assignment by radiologists on SM was similar to density assignment on standard 2-D mammogram.
