Abstract
This work presents patient radiation dose data for pediatric interventional cardiology procedures in a large hospital in Colombia.
The data collection period was from April 2020 to July 2022. The local DRLs were calculated as the 3rd quartile of patient dose data distributions for kerma area-product (Pka) values. The sample of collected clinical procedures (255) was divided into diagnostic and therapeutic procedures and grouped into five weight and five age bands.
The Pka differences found between diagnostic and therapeutic procedures were statistically in all weight and age bands, except the group between 1-5 years. The local DRLs were 69 Gy/cm2 (< 5 kg), 3.44 Gy/cm2 (5-<15 kg), 8.87 Gy/cm2 (15-<30 kg), 10.51 Gy/cm2 (30-<50 kg) y 22.61 Gy/cm2 (50-<80 kg), respectively.
In conclusion, from comparing our results with other existing DRL values, we are similar to other centers and scope to continue optimizing the radiation dose values. This will contribute to setting national diagnostic reference levels (DRLs) for Colombia in the near future.
