Evaluation of average glandular dose and investigation of the relationship with compressed breast thickness in dual energy contrast enhanced digital mammography and digital breast tomosynthesis
European Journal of Radiology Mar 13, 2020
Fusco R, Raiano N, Raiano C, et al. - This study was undertaken to investigate the dose of Dual-energy contrast-enhanced digital mammography (CEDM) and digital breast tomosynthesis (DBT) and to investigate the relationship between average absorbed glandular dose (AGD), compressed breast thickness (CBT) and compression force (CF). Researchers carried out All CEDM and DBT examinations in craniocaudal (CC) and mediolateral oblique (MLO) views. They recorded exposure parameters of 135 mammographic procedures using AEC (automatic exposure control) mode. In mammography, the dose values of both techniques meet the recommendations for maximum dose. A significant difference was found between AGD for CEDM and DBT exposure in different views (AGD in CC views had the lowest value) and that CBT could influence the AGD while CF was not correlated to AGD.
