Eur J Epidemiol. 2014; 29(4): 293-301 The Dutch Pediatric CT Study follows children who underwent CT scanning in the Netherlands to assess associations between low-dose radiation from medical imaging and subsequent cancer risk, particularly leukaemia and brain tumours. Published results contributed to the growing international evidence base on radiation risks from paediatric CT, informing radiation protection guidance for diagnostic imaging in children.
