Abstract
Abstract This work aims to determine the diagnostic reference levels (DRL) for scintigraphy exams (SE) in the nuclear medicine (NM) department of the Oncology and Haematology Hospital, Mohammed VI University Hospital Centre of Marrakech region of Morocco (OHH, Med VI UHC-MM). These levels were based on the most recent recommendations from the ICRP in 2023. We compared the derived DRL with the published literature. The methodology applied consisted of using data recorded retrospectively in the files of patients who had undergone scintigraphy examinations in the nuclear medicine department during the period 2021–2023. Typical values (DRLs), based on the median of the distribution of administered activity (MBq) for bone (HMDP-99mTc), thyroid (99mTc), parathyroid (Sestamibi-99mTc and 99mTc), renal (DMSA-99mTc) scans, octreoscan (Tectrotyd-99mTc), pulmonary (Pulmosic-99mTc), cardiac (Sestamibi-99mTc) (stress and rest), and cerebral (HMPAO-99mTc) were 666 MBq, 144 MBq, (86 MBq, 666 MBq), 136 MBq, 555 MBq, 144 MBq, (333 MBq and 1073 MBq), and 703 MBq, of the different types of tests. In general, the results showed that the new DRLs were higher than the national diagnostic reference levels observed in French in 2021 and lower than those observed in South Korea in 2019, Croatia in 2020, and Switzerland in 2023.
