Local Diagnostic Reference Levels for Paediatric Head CT Procedures.

Results of this study showed that settled new local DRLs of head CT examinations were 2-4 times lower than national DRLs and about 2 times lower than European DRLs. Moreover, the study indicated that paediatric head CT doses are significantly lower in comparison with those indicated in the majority of published data from other hospitals over the last 6 years. Patient dose assessment and local DRLs establishment plays important role in future exposure optimisation.
