Abstract
Computed tomography (CT) is a widespread diagnostic modality that is commonly associated with relatively high patient doses. Hence, optimization of radiation protection of the patients from CT examinations is extremely important. An integrant part of radiation protection in medicine is a system of diagnostic reference levels (DRLs). The aim of the study was to evaluate the possibility of establishing DRLs for typical CT examinations on national level in the Russian Federation. The study is based on the dose surveys performed in different regions of Russia in 2009-2017. Data was collected on the most
common native and multiphase CT examinations as well as whole body CT as a part of positron emission tomography combined with computed... (More)

An integrant part of radiation protection in medicine is a system of diagnostic reference levels (DRLs). The aim of the study was to evaluate the possibility of establishing DRLs for typical CT examinations on national level in the Russian Federation. The study is based on the dose surveys performed in different regions of Russia in 2009-2017. Data was collected on the most
common native and multiphase CT examinations as well as whole body CT as a part of positron emission tomography combined with computed tomography (PET/CT) examinations. Establishment of DRLs on the region level in Russia is
complicated due to the high number of regions and limited availability of dose data. Comparison between typical dose distributions indicated no significant regional differences, hence allowing establishing DRLs on the national level. The 75% percentiles of both DLP and effective dose distributions were proposed as the preliminary values of national DRLs. It was proposed to establish DRLs for whole native CT examinations or for one phase of multiphase CT examination. (Less)
