  1. Data for 2ABD and AGD 100% glandularity are presented as mean ± standard deviation. The comparison was carried out by considering all mammographic devices. The exposure parameters were chosen as close as possible to the corresponding automatic exposure control settings for a given phantom thickness. For the AGD calculation by the Dance method, the measured air kerma was employed. For the Amulet Innovality devices both the standard acquisition mode and high-resolution acquisition mode (*) were employed
