Johanna M. Meulepas,Cécile M. Ronckers,Anne M. J. B. Smets,Rutger A.J. Nievelstein,Patrycja Gradowska,Choonsik Lee,Andreas Jahnen,Marcel van Straten,Marie Claire Y. de Wit,Bernard A. Zonnenberg,Willemijn M. Klein,J.H.M. Merks,Otto Visser,Flora E. van Leeuwen,Michael Hauptmann +14 more
TL;DR: Evidence is found that CT-related radiation exposure increases brain tumor risk following exposure to low-dose ionizing radiation from CT scans in childhood, and incidence of brain tumors was higher in the cohort of children with CT scans, requiring cautious interpretation of the findings.
Journal ArticleDOI

TL;DR: In this article, the risk of developing cancer, specifically leukaemia, tumours of the central nervous system and lymphoma, before the age of 15 years in children previously exposed to computed tomography (CT) in Germany was assessed.
Journal ArticleDOI
Computed tomographies and cancer risk in children: a literature overview of CT practices, risk estimations and an epidemiologic cohort study proposal

TL;DR: An historical cohort study is conducted to investigate the cancer incidence in paediatric patients exposed to CT before the age of 15 in Germany and computation of standardized incidence ratios using population-based incidence rates for childhood cancer is described.

TL;DR: By focusing on the issues which challenge the validity of risk estimates from CT exposures, EPI-CT will be able to address limitations of previous CT studies, thus providing reliable estimates of risk of solid tumours and leukaemia from children's CT exposures and scientific bases for the optimisation of paediatric CT protocols and patient protection.
