Background/Introduction
In the last years also in Slovakia it was found a significant increase of the number of CT examinations,
performed not only in the group of adult patients,
but also for children.
Because the number of CT procedures performed in a year,
accounts for more than 50% of the total population dose from the medical examinations and it is well known that the lifetime cancer risk from radiation exposure in childhood for a given dose is much higher for the younger age groups compared to the adults,
there is a need to thoroughly require the strict application of the basic principles of radiation protection in the everyday practice of paediatric imaging.
One of the important tools for the effective optimization and reduction of the doses in paediatric imaging is to specify appropriate diagnostic reference values plotted as a function of the size of the examined children and to compare mandatory the doses received by the patients with normalized DRLs.
