CT departments (n=211) were surveyed nationally (June 2011–January 2012) and CT protocol information and dose data were collected, as were retrospective age-categorised paediatric CT data from three national paediatric centres. The proposed national CT DRLs (CTDIvol) for adults were 75, 18, 14, 18, 17, 36, 22, 27 and 16 mGy for head, neck, chest, abdomen, pelvis, cervical, dorsal, lumbar and joints, respectively. The levels for paediatric head and chest examinations were as follows: 48 and 2 mGy (newborns), 50 and 6 mGy (5 y olds), 70 and 6 mGy (10 y olds) and 72 and 7 mGy (15 y olds). A limited number of current paediatric protocols aligned to recommended international age categorisations. Portuguese DRLs were generally higher than European recommendations, suggesting potential for optimisation. The need for greater standardisation of age-categorised paediatric protocols was identified.||Type of material:||Journal Article||Publisher:||Oxford University Press||Journal:||Radiation Protection Dosimetry||Volume:||158||Issue:||3||Start page:||307||End page:||317||Copyright (published version):||2013 the Authors||Keywords:||Computed tomography (CT); Radiation dosage; Radiation protection||DOI:||10.1093/rpd/nct226||Language:||en||Status of Item:||Peer reviewed|
