Diagnostic Reference Levels in Interventional Pediatric Cardiology: Two-Year Experience in a Tertiary Referral Hospital in Latin America

The goal of the present study was to propose first local diagnostic reference levels (DRLs) for interventional pediatric cardiology procedures in a large hospital Colombia. data collection period from April 2020 July 2022. DRLs were calculated as 3rd quartile patient-dose distributions kerma-area product (Pka) values. sample collected clinical (255) divided into and therapeutic grouped five weight age bands. Pka differences found between statistically significant all bands, except 1–5-year group. bands 3.82 Gy·cm2 (<5 kg), 7.39 (5–<15 19.72 (15–<30 28.99 (30–<50 81.71 (50–<80 respectively. For 3.97 (<1 y), 9.94 (1–<5 20.82 (5–<10 58.00 (10–<16 31.56 (<16 In conclusion, when comparing our results with other existing DRL values, we that they are similar centers thus there is scope continue optimizing radiation dose This will contribute establishing national Colombia near future.
