- Аннотация: to analyze radiation exposure due to computed tomography (CT) of brain, chest, abdomen and pelvis in a large multi-field federal hospital and feasibility of low-dose CT-examinations.\ Retrospective analysis was performed using data from electronic patient records and PACS from a single multi-field hospital. Data were obtained from 1626 records of patients (794 men, 832 women; age range 17-93) scanned with 3 MDCT during one year. CT-examinations of good quality were selected, volumetric CT dose index (CTDI) and dose-length product (DLP) were collected for each of them. The effective doses (ED) were calculated using the normalized coefficients according to Russian Guidance. RESULTS. Number and structure of CT-examinations for the years 2012-2014 in a multi-field hospital were analyzed. The mean effective dose (M ± m) values with/without contrast medium (respectively), according to anatomical areas were as follows: brain–2.34 ± 0.03/3, 52 ± 0.23, chest–4.83 ± 0.11/11.02 ± 0.82, abdomen-pelvis–9.81 ± 0.40/36.6 ± 1.17, chest-abdomen-pelvis - 12.41 ± 0.79/35.63 ± 1.81 mSv. CONCLUSION. Results of this study give an example of CT dose values and distribution in a multi-field hospital. They are compa- rable with reference levels published of other authors. This expe- rience should be expanded for creation of CT national reference values and for co-operation with international initiatives (EUROSAFE projects).
