[CT examinations in children].

Computed tomography (CT) accounts for a significant proportion of radiation exposure patients are exposed to during diagnosis, which means that particularly strict indications need to be observed especially where children are concerned. Numerous factors influence the level of radiation exposure, only a few of which can be changed by the radiologist and radiographer. Sound knowledge of the links between technical implementation and the resultant image quality needed for the diagnosis can dramatically reduce the radiation patients are exposed to, which in turn has an influence on the indications. In the present paper the radiologist is given tools for optimisation of CT examinations in children and accepted indications for CT of all body regions are presented.
