Insights
This study establishes preliminary diagnostic reference levels (DRL) for pediatric interventional cardiology in Argentina. These radiation dose levels aim to minimize patient exposure during fluoroscopy-guided procedures.
Area of Science:
- Medical Physics
- Radiology
- Pediatric Cardiology
Background:
- Radiation dose optimization is crucial in pediatric interventional cardiology.
- Establishing local diagnostic reference levels (DRL) aids in dose management.
- The OPRIPALC program promotes radiation protection in Latin America.
Purpose of the Study:
- To propose preliminary local diagnostic reference levels (DRL) for pediatric interventional cardiology (PIC) procedures in Argentina.
- To stratify DRLs based on patient age and weight ranges.
- To contribute to radiation dose optimization in pediatric fluoroscopy.
Main Methods:
- Data collection within the OPRIPALC program framework.
- Calculation of DRLs based on pediatric patient weight and age groups.
- Comparison of local DRLs with international findings.
Main Results:
- Preliminary DRLs were established for various pediatric weight and age groups.
- Specific DRL values presented: 7.1 Gy·cm² (<5 kg), 10.7 Gy·cm² (5-15 kg), 18.0 Gy·cm² (15-30 kg), 15.9 Gy·cm² (30-50 kg), 28.2 Gy·cm² (50-80 kg).
- Age-based DRLs: 5.3 Gy·cm² (<1 yr), 11.2 Gy·cm² (1-5 yrs), 19.6 Gy·cm² (5-10 yrs), 21.4 Gy·cm² (10-16 yrs).
Conclusions:
- The study provides initial DRLs for PIC in Argentina.
- The established DRLs are comparable to international values.
- Significant potential exists for further radiation dose optimization in pediatric interventional procedures.
Abstract:
The aim of this work was to propose a preliminary local diagnostic reference levels (DRL) for pediatric interventional cardiology (PIC) procedures in Argentina, for different ranges of age and weight. This work has been conducted in the framework of the "Optimization of Protection in Pediatric Interventional Radiology in Latin America and the Caribbean" (OPRIPALC) program coordinated by the World Health Organization and the Pan American Health Organization in cooperation with the International Atomic Energy Agency to ensuring that radiation exposures of pediatric patients are the minimum necessary during fluoroscopy-guided interventional procedures. The local DRL values presented in this paper by weight group and age group were 7.1 Gy·cm2 (<5 kg), 10.7 Gy·cm2 (5-15 kg), 18.0 Gy·cm2 (15-30 kg), 15.9 Gy·cm2 (30-50 kg), and 28.2 Gy·cm2 (50-80 kg) and 5.3 Gy·cm2 (<1), 11.2 Gy·cm2 (1 to 5<), 19.6 Gy·cm2 (5 to 10<), and 21.4 Gy·cm2 (10 to 16<), respectively. Our dose results are among the values found in other international studies; however, there is great potential for dose optimization.
