The aim of this study was to optimise paediatric conventional radiology examinations applying the ED without compromising the clinical diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>Automatic dose management software (ADMS) was used to analyse 2678 studies of children from birth to 5 years of age, obtaining local diagnostic reference levels (DRLs) in terms of entrance surface air kerma. Given local DRL for infants and chest examinations exceeded the European Commission (EC) DRL, an optimisation was performed decreasing the kVp and applying the automatic control exposure. To assess the image quality, an analysis of high-contrast resolution (HCSR), signal-to-noise ratio (SNR) and figure of merit (FOM) was performed, as well as a blind test based on the generalised estimating equations method.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>For newborns and chest examinations, the local DRL exceeded the EC DRL by 113%. After the optimisation, a reduction of 54% was obtained. No significant differences were found in the image quality blind\u00a0test. A decrease in SNR (\u221237%) and HCSR (\u221268%), and an increase in FOM (42%), was observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>ADMS allows the fast calculation of local DRLs and the performance of optimisation procedures in babies without delay.
