ABSTRACT
UNLABELLED The aim of this study was to collect administered activities of important nuclear medicine diagnostic examinations and to identify frequencies as well as age distributions in the light of hybrid devices in Austria. Based on the survey data a re-evaluation of dose reference levels for nuclear medicine has been published in June 2010 in the novella of the Austrian Medical Radiation Protection Regulation (MedStrSchV) (8), also an estimate of the average individual doses of the total population. Accurate data on nuclear medicine studies of 34% of all Austrian nuclear medicine units could be collected. RESULTS:
Extrapolated there are about 150000 nuclear medicine examinations per year performed in Austria. The median age of patients is thereby 62 years. The results of this study resulted in 65% of the dose reference values to change, whereas 48% had to be revised downwards and 17% upwards. Additionally, 5 new reference values were included in the list; three more were taken out, however. The estimation of the individual effective patient dose for each offered examination was on average 4.7 mSv. An extrapolation based on the total exposure of the population with regard to uninvolved persons and children led to 0.07 mSv per year by nuclear medicine examinations.CONCLUSION:
The published diagnostic reference values correspond to the normal investigative practice in Austria and are compliant with most international recommendations. The term "optimal value" has been removed from the text of the law, because such wording would be misleading.
