4 Conclusion
This study realized at the OHH of Med VI UHC is the first one in Morocco to determine local DRLs for scintigraphy exams, which revealed some values higher than those observed in several other countries. By conducting this research, we hope to contribute to the achievement of national DRLs for NM in Morocco, promoting the development of a dose and activity registration national database, essential to optimize the practices and activities administered, and thus the patient radioprotection. Using national DRLs in future research protocols and clinical routine will significantly reduce patient exposure to medical radiation in Morocco.
