There is substantial need for optimizing radiation protection in nuclear medicine imaging studies. However, the diagnostic reference levels (DRLs) have not yet been established for nuclear medicine imaging studies in Korea.
The data of administered activity in 32 nuclear medicine imaging studies were collected from the Korean Society of Nuclear Medicine (KSNM) dose survey database from 2013 and 2014. Through the expert discussions and statistical analyses, the 75th quartile value (Q3) was suggested as the preliminary DRL values. Preliminary DRLs were subjected to approval process by the KSNM Board of Directors and KSNM Council, followed by clinical applications and performance rating by domestic institutes.
DRLs were determined through 32 nuclear medicine imaging studies. The Q3 value was considered as appropriate selection as it was generally consistent with the most commonly administered activity. In the present study, the final version of initial DRL values for nuclear medicine imaging in Korean adults is described including various protocols of the brain and myocardial perfusion imaging.
The first DRLs for nuclear medicine imaging in Korean adults were confirmed. The DRLs will enable optimized radiation protection in the field of nuclear medicine imaging in Korea.
在核医学成像研究中，非常需要优化辐射防护。然而，韩国尚未建立核医学成像研究的诊断参考水平（DRL）。
从韩国核医学协会（KSNM）2013年和2014年的剂量调查数据库中收集了32项核医学成像研究中的给药活度数据。通过专家讨论和统计分析，建议将第75四分位数（Q3）值作为初步DRL值。初步DRL需经KSNM董事会和KSNM理事会批准，随后由国内机构进行临床应用和性能评级。
通过32项核医学成像研究确定了DRL。Q3值被认为是合适的选择，因为它通常与最常用的给药活度一致。在本研究中，描述了韩国成年人核医学成像初始DRL值的最终版本，包括脑和心肌灌注成像的各种方案。
确认了韩国成年人核医学成像的首个DRL。这些DRL将使韩国核医学成像领域的辐射防护得到优化。
