Participant images with density assessment. Images from the Laboratory for Individualized Breast Radiodensity Assessment (LIBRA) of a woman without cancer, 47 years old, who participated in the Malmö Breast Tomosynthesis Screening Trial. The woman was not recalled from screening. Breast density assessment with the LIBRA showed breast density corresponding to the fourth quintiles of both breast percent density and absolute dense area. Left images show the craniocaudal (upper) and mediolateral oblique (lower) view from digital mammography without density assessment. Right images show the same projections with density assessment. The total breast areas are marked in red and the dense areas in green
