Abstract

Introduction

This study establishes weight-based diagnostic reference levels (DRLs) for paediatric fluoroscopic procedures by conducting a radiation dose survey for children under 50 kg.

Methods

Utilizing data from 859 fluoroscopic examinations, the study calculated local DRLs across seven common procedures, categorizing patients by weight to reflect the large size variation among paediatric patients. Our local DRLs were compared to United Kingdom National Diagnostic Reference Levels (NDRLs).

Results

The results show that radiation doses at our centre were consistently lower than national guidelines, with an average of 16 % of NDRLs. Doses were lowest for fluoroscopy studies of swallowing (3–10 % of NDRLs), and highest for MCUGs and upper GI studies (10–42 % of NDRLs).

Conclusion

This research highlights the importance of weight-based DRLs to enhance radiation safety in paediatric imaging and advocates for the broader adoption of such practices across healthcare facilities.

Implications for practice

The results emphasize the need for regular updates of national DRLs and encourage widespread reporting of paediatric dose data by weight, to optimize radiation protection strategies.
