Background Previous paediatric diagnostic reference levels (PDRL) literature reviews for
commonly performed procedures of the brain, chest and abdomen revealed wide DRL …

Introduction As computed tomography (CT) examinations have considerably risen, safe
operation is essential to reduce the patients' dose. The main objective of this study was to …

Objective Using pediatric anthropomorphic phantoms (APs), we aimed to determine the
scanning tube voltage/current combinations that could achieve optimal image quality and …

Introduction: The paediatric radiation dose has never been studied in Sri Lanka, nor has a
national diagnostic reference level (NDRL) established. Therefore, the primary aim of this …

Background Radiation exposures from computed tomography (CT) in children are
inadequately studied. Diagnostic reference levels (DRLs) can help optimise radiation doses …

This study aimed to establish dose reference level (NDRLSSDE) based on size-specific
dose estimate (SSDE) derived using effective diameter (Deff) for adult chest and abdomen …

Computed tomography (CT) frequency is approximately 11% of medical radiological
procedures. Nevertheless, CT examinations contribute up to 70% collective doses. CT …

Objective: To present the results following a UK national patient dose audit of paediatric CT
examinations, to propose updated UK national diagnostic reference levels (DRLs) and to …

Purpose Accumulating evidence from epidemiological studies that pediatric computed
tomography (CT) examinations can be associated with a small but non-zero excess risk for …

Background The American Association of Physicists in Medicine (AAPM) report 293 is more
accurate than report 220 in evaluating the absorbed radiation dose during head computed …
