Abstract
In order to establish National Diagnostic Reference Levels (DRLs) for mammography examinations, Entrance Skin Air Kerma (ESAK), Entrance Skin Dose (ESD) and Average Glandular Doses (AGDs) were calculated for a total of 25624 cranio-caudal (CC) and mediolateral oblique (MLO) projections of 6309 patients for 40-49 and 50-64 age groups. The average ESAK and ESD values for both age groups were found to be higher in MLO projections compared to CC projections. The minimum and maximum values of AGDs were determined as 0.4 mGy and 7.9 mGy for both projections. The maximum numbers of AGDs for CC and MLO projections were calculated in the range of 1.1-1.5 mGy and 1.6-2.0 mGy respectively. The third quartile values of AGDs were calculated for each compressed breast thickness (CBT) between 20 mm and 99 mm. The first National DRLs of the country were established for each 10 mm CBT in mammography examinations.
