[Results of the Austrian CT Dose Study 2010: Typical effective Doses of the most frequent CT examinations.]

CONCLUSION: Variations between CT operators are generally moderate for most operators, but in some indications the ratio between the minimum and the maximum of average dose to the typical standard patients exceeds a factor of 4 or even 5. Therefore, comparing average doses to Diagnostic Reference Levels (DRLs) and optimizing protocols need to be encouraged.
