摘 要:The aim of this study was to report the diagnostic reference levels (DRLs) corresponding to different compressed breast thickness (CBT) ranges. To achieve this, mammographic examinations with 187,788 exposures were analysed. The mean average glandular (AGD) dose was calculated per view, examination, and center. Moreover, the DRL values corresponding to different CBT ranges were reported. The result of the mean AGD per view was found to be 1.36 mGy for craniocaudal (CC) and 1.54 mGy for Mediolateral oblique (MLO), while the mean AGD per examination for all women was 1.45 mGy. The DRL values corresponding to CBTs between 20 to 79 mm ranges were below 2 mGy. These results were from a population of mean age = 49 +/- 8 years and mean CBT = 58 +/- 8 mm, and was imaged with mean exposures of 29 +/- 1 kVp and 74 +/- 31 mAs, and a mean compression force of 135 +/- 37 N. In conclusion, good mammography practice has been shown, as DRL values are within the limits suggested by the international organizations.
