초록

Mammography is an important medical tool used to diagnose breast cancer. The usageof mammography is continuously increasing due to the development of the medical industry inKorea. The glandular tissue which is sensitive to radiation is exposed during mammography, so itis necessary to manage the patient dose for mammography. Therefore, the objective of this studyis to evaluate the radiation dose for mammography and to investigate and analyze domestic andforeign diagnostic reference levels. In this study, radiation dose assessment methodology based onMonte-Carlo was established for the evaluation of patient radiation dose by mammography. Thestudies on the diagnostic reference level of countries and associations such as the United States,Australia, Spain, Ireland, Bulgaria, and Slovenia were investigated. In Korea, the studies on themammography diagnostic reference level conducted by the Ministry of Food and Drug Safety(MFDS) and the Korea Centers for Disease Control and Prevention (KCDC) were investigated.
As a result of evaluating the mean glandular dose and effective dose by mammography usingthe MCNP program, the mean glandular dose and effective dose for the compression breastthickness range of 4~5 cm which is largest number of patients in Korea were 1.36 mGy, 0.163mSv and 1.34 mGy, 0.161 mSv for CC and MLO. In a study conducted by the KCDC in 2018,the mammography diagnostic reference level for phantom and patient was established. Thediagnostic reference level for phantom was 1.59 mGy, which was 14% and 18% higher thanKorea in 2007 and Australia, and 26%, 45%, 7% lower than US, Bulgaria, and Slovenia. Thediagnostic reference level for patient was 1.97 and 1.98 mGy in the CC and MLO, similar to Spainand higher than other countries and associations. The result of patient radiation dose evaluationfor mammography and domestic and foreign diagnostic reference level analysis conducted in thisstudy can be used as basic data for reducing patient dose by mammography in Korea.
