The collected data included characteristics of CT scanners, frequency of CT exams per anatomical region, dose indices CTDIvol and dose-length product (DLP). National DRLs were proposed at the 75th percentile of median dose indices distributions for four common CT protocols: head without contrast (brain examinations for stroke and trauma), routine chest without contrast, single-phase contrast-enhanced CT of abdomen and pelvis and oncology protocol (chest\u2013abdomen\u2013pelvis). The results showed 4- to 9-fold variations of median dose indices between CT scanners for the same type of examination. The following values of the CTDIvol and DLP were proposed as national DRLs: 59\u00a0mGy and 1130\u00a0mGy\u2022cm for head, 14\u00a0mGy and 492\u00a0mGy\u2022cm for chest, 22\u00a0mGy and 845\u00a0mGy\u2022cm for abdomen\/pelvis and 2120\u00a0mGy\u2022cm for oncological protocol.<\/jats:p>","DOI":"10.1093\/rpd\/ncad157","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T21:30:15Z","timestamp":1684877415000},"page":"1142-1150","source":"Crossref","is-referenced-by-count":6,"title":["SURVEY OF COMPUTED TOMOGRAPHY PRACTICE IN UKRAINE AND ESTABLISHMENT OF NATIONAL DIAGNOSTIC REFERENCE LEVELS FOR MOST COMMON CT EXAMINATIONS OF ADULTS"],"prefix":"10.1093","volume":"199","author":[{"given":"Larysa","family":"Stadnyk","sequence":"first","affiliation":[{"name":"Central Laboratory of Radiation Safety and Dosimetry of Medical Exposure, Grigorev Institute for Medical Radiology and Oncology , 82 Pushkinska Street, Kharkiv 61024 , Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Nosyk","sequence":"additional","affiliation":[{"name":"Central Laboratory of Radiation Safety and Dosimetry of Medical Exposure, Grigorev Institute for Medical Radiology and Oncology , 82 Pushkinska Street, Kharkiv 61024 , Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7911-5534","authenticated-orcid":false,"given":"Elena","family":"Tonkopi","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Dalhousie University , PO BOX 9000, 1276 South Park Street, Halifax, NS B3H 2Y9 , Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Boguslavska","sequence":"additional","affiliation":[{"name":"State Nuclear Regulatory Inspectorate of Ukraine , 9\/11 Arselna Street, Kyiv 01001 , Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenia","family":"Vassileva","sequence":"additional","affiliation":[{"name":"Radiation Protection of Patients Unit , International Atomic Energy Agency, , PO Box 100, Vienna 1400 , Austria"},{"name":"Vienna International Centre , International Atomic Energy Agency, , PO Box 100, Vienna 1400 , Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"issue":"1","key":"2023062312150179700_ref1","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1148\/radiol.10100640","article-title":"National trends in CT use in the emergency department: 1995\u20132007","volume":"258","author":"Larson","year":"2011","journal-title":"Radiology"},{"key":"2023062312150179700_ref2","volume-title":"United Nations Scientific Committee on the Effects of Atomic Radiation UNSCEAR 2020\/2021 Report to the General Assembly, with Scientific Annexes","author":"Sources, Effects and Risks of Ionizing Radiation","year":"2022"},{"key":"2023062312150179700_ref3","volume-title":"Radiation Protection \u2116 180: Medical Radiation Exposure of the European Population","author":"European Commission","year":"2014"},{"issue":"4","key":"2023062312150179700_ref4","doi-asserted-by":"crossref","first-page":"1828","DOI":"10.1007\/s00330-019-06523-y","article-title":"Patients undergoing recurrent CT scans: assessing the magnitude","volume":"30","author":"Rehani","year":"2020","journal-title":"Eur.
