[Results of the Austrian CT dose study 2010: typical effective doses of the most frequent CT examinations].

Purpose: To determine typical doses from common CT examinations of standard sized adult patients and their variability between CT operators for common CT indications.

Materials And Methods: In a nationwide Austrian CT dose survey doses from approx. 10,000 common CT examinations of adults during 2009 and 2010 were collected and "typical" radiation doses to the "average patient", which turned out to have 75.

Diagnostic reference levels in pediatric radiology in Austria.

Background: Because of the higher sensitivity to radiation in children, optimization plays an essential role in pediatric radiology. Diagnostic reference levels are a helpful tool to optimize patient dose for standard radiographic procedures.

Methods: A nationwide survey was conducted to determine doses and variation in average dose applied to children for standard X-ray examinations.
