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 Apr 17, 2020
Fusco R, Raiano N, Raiano C, et al. - This study was undertaken to measure the dose of Dual energy contrast enhanced digital mammography (CEDM) and digital breast tomosynthesis (DBT) and to evaluate the association between average absorbed glandular dose (AGD), compressed breast thickness (CBT) and compression force (CF). Researchers conducted all CEDM and DBT examinations in cranio-caudal (CC) and medio-lateral oblique (MLO) view. They measured exposure parameters of 135 mammographic procedures that using AEC (automatic exposure control) mode. AGDs were estimated. They further performed Kruskal Wallis test. The data indicate that in mammography, dose values of both techniques meet the recommendations for maximum dose. A significant difference was noted between AGD for CEDM and DBT exposure in different views (AGD in CC views had the lowest value) and that CBT could affect the AGD while CF was not correlated to AGD.
