Abstract

Objective: To determine the local diagnostic reference levels (local DRL) for screening mammography at Tanyawej Breast Center, Songklanagarind Hospital on digital mammography Hologic Selenia dimensions.

Materials and Methods: Retrospective data of screening mammography were collected from 400 patients, 200 patients for 2D technique and 200 patients for Combo technique. The women ages between 40-75 years old who have the compressed breast thickness between 40-69 mm. between 1 January 2018 - 30 September 2019. The patient data and exposure parameters were collected as follows: average glandular dose (AGD, mGy); entrance surface air kerma (ESAK; mGy); compressed breast thickness (CBT, mm); compression force (CF, N); peak kilovoltage (kVp); tube current-time (mAs); target and filter (W/Rh, W/Ag); patient age (year); and patient positioning in terms of RCC, LCC, RMLO, LMLO were also recorded.

Results: The results showed that the AGD using compressed breast thickness in between 40-69 mm at the percentile 75 were 2.07 mGy and mGy for 2D technique and Combo-technique, respectively. The average glandular dose over the percentile 75 was 33% in 2D technique and Combo-technique.

Conclusion: The local DRLs for screening mammography using 2D and combo techniques obtained in this study were 2.07 mGy and 2.14 mGy, respectively.
