7j The nuclear medical diagnostic procedures at the hospitals in Sofia over a period of ten years ―from 1990 to 2000 ― structure, number and doses

摘要

The aim of this study is to analyze the structure and the number of nuclear diagnostic procedures at hospitals in Sofia over a period often years (from 1990 to 2000); to calculate the effective doses received by patients; to compare the results from different hospitals. We have developed a form in order to collect the necessary information from hospitals /nuclear laboratories/. The information has been collected according to examined organ, applied radioactive pharmaceutical and injected activity [MBq], patient's age and sex. The effective doses have been calculated using transition coefficients /1/ for each of the applied radioactive Pharmaceuticals and for each of the diagnostic procedures. We have received the information and calculated the doses. We have compared the data from different hospitals /nuclear laboratories/. The results show that the doctors in different hospitals have used different radioactive Pharmaceuticals and applied different activities for one and the same procedure.
