Paediatric interventional cardiology in Costa Rica: diagnostic reference levels and estimation of population dose
The goal of the present study was to propose a set of national diagnostic reference levels (DRLs) in
Costa Rica for paediatric interventional cardiology (IC) procedures classified by age and weight and
to estimate the collective dose of the paediatric population from these intervention practices. The
data collection period was May 2016 to May 2017. The third quartile of patient dose data
distributions for kerma –area product (KAP) values was set as the national DRLs. A sample of 154
paediatric IC procedures (collected in the national paediatric hospital with a single x-ray system)
was used and divided into four age ranges and five weight ranges. The national DRLs obtained for
KAPs by age range were 1.79 Gy cm 2 (
