title: What all physicians should know about the potential radiation risk that computed tomography poses for paediatric patients.
abstract: The repeated use of CT imaging raises a child's radiation exposure, overall radiation accrual and future cancer risks. However, our review suggests that these risks can be considerably reduced by physicians, radiologists and academic bodies, through proper justification, optimisation and dose limitation.
  
  
  CONCLUSIONS
  Computed tomography poses a potential risk of radiation-induced cancer in children. The physician must weigh up the overall risks and benefits of CT before referring a child for imaging.
