ABSTRACT
The goal of this work was to determine U.S. diagnostic reference levels (DRLs) and achievable administered activities (AAAs) for adult renal scintigraphy. Methods:
Under an Institutional Review Board-approved protocol, data were collected from the Intersocietal Accreditation Commission during one 3-y accreditation cycle encompassing 110 facilities. Elements included radiopharmaceutical, administered activity, practice type, and examination volume. DRLs and AAAs were calculated and compared with non-U.S. values and societal recommendations as available.Results:
Ninety-three facilities provided data on 99mTc-mercaptoacetyltriglycine (99mTc-MAG3), and 15 provided data on 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) for adult renal scintigraphy exams. Analysis demonstrated a DRL of 392.2 MBq (10.6 mCi) for 99mTc-MAG3 and 531.7 MBq (14.4 mCi) for 99mTc-DTPA, with an AAA of 370 MBq (10 mCi) for 99mTc-MAG3 and 445.9 MBq (12.1 mCi) for 99mTc-DTPA.Conclusion:
The resultant calculated novel U.S. DRLs and AAAs may serve as benchmarks that nuclear medicine facilities may use to refine renal scintigraphy protocols, reduce patient doses, and potentially guide future societal guideline recommendations.Palavras-chave
