“…It is not appropriate to adjust the administered activity to the lowest possible level but similar to that of DRL [10]. Moreover, DRL values are not considered as limits, and the highest priority for any diagnostic examination is to achieve sufficient image quality [1,2,7]. Therefore, DRLs should not be used as evidences for legal restriction or insurance coverage, which was suggested as a potential concern during the expert discussion.…”

“…It is a form of investigation level, which applies to an easily measured quantity, usually the administered activity (MBq) in nuclear medicine imaging studies. However, as DRL is recommended to avoid excessive radiation exposure to patients while maintaining sufficient image quality, it should not be applied as a dose constraint or dose limit [2]. In 1999, the European Commission published the Radiation Protection 109 [3] and stated that DRLs should be set by member states under consideration of individual national or regional circumstances such as the availability of equipment and training under the Radiation Protection 180 [4].…”

Purpose 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. Materials and Methods 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. Results 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. Conclusion 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.

“…Optimization refers to the principle that the radiation dose to the patients should be "as low as reasonably achievable (ALARA)". The main efforts for optimization of radiation protection in nuclear medicine have been made in terms of the reduction of administered radiopharmaceutical activity [9]. The ALARA principle is important for patients as well as workers.…”

Dose calibrators are used to measure the amount of radioactive to be given to the patient. It is necessary to determine the correct dose and measure the amount of radioactive material with the least possible error. To minimize these potential errors, quality control (QC) tests should be carried out periodically according to the United States Nuclear Regulatory Authority (NRC). ATOM LAB 400 (serial number:11070208 ) and 500 (serial number: 15091215) dose calibrators that are actively used in our clinic were used. The aim of this study is to compare with another recently calibrated dose calibrator to verify the dose calibrator that needs to be updated is working properly. QC tests were performed on both dose calibrators. Test results of the currently certified dose calibrator and ATOM LAB 400 dose calibrator whose certificate will be updated were found to be compatible with each other. The tests performed on both dose calibrators remained with the error limits. The calibration certificate of the ATOM LAB 400 calibrator has been updated in accordance with NRC protocol.

“…rhTSH is preferred as an adjunctive diagnostic tool for serum Tg level measurement in patient follow up and for pretherapeutic stimulation. 9,10 I-131 Whole body scan (WBS) is used to detect thyroid remnants, regional or distant metastases, and the serum Tg level is preferred for detecting residual or recurrent disease in DTC patients. 9 TSH stimulation is needed to increase iodine uptake for RAI therapy or I-131 WBS.…”
