This study estimated the fetal and pediatric doses from chest CT scans. Organ doses and effective doses were calculated using the VirtualDose-CT software. Two groups of computational human phantoms, pregnant females and pediatric patients were used in this study. The results of doses normalized to volumetric CT Dose Index (CTDIvol) can be used universally for other dosimetry studies. Based on our calculations and international survey data of CTDIvol, fetal absorbed doses from COVID-19-related chest CT were found to be 0.04\u20130.36, 0.05\u20130.44 and 0.07\u20130.61\u00a0mGy for 3, 6 and 9\u00a0months of pregnancy, respectively. When the scan range is extended to the abdominal region, fetal doses increase by almost 4-fold. Effective doses for COVID-19-related chest CT were 1.62\u201313.77, 1.58\u201313.46, 1.57\u201313.33 and 1.29\u201310.98\u00a0mSv for the newborn, 1-, 5- and 10-y-old children, respectively. In addition, the effects of specific axial scan ranges exceeding the thorax region were evaluated. Although doses from chest CT scans are small, such data allow radiologists and patients to be informed of the dose levels and ways to avoid unnecessary radiation.<\/jats:p>","DOI":"10.1093\/rpd\/ncac225","type":"journal-article","created":{"date-parts":[[2022,11,14]],"date-time":"2022-11-14T15:20:15Z","timestamp":1668439215000},"page":"52-60","source":"Crossref","is-referenced-by-count":4,"title":["ESTIMATION OF FETAL AND PEDIATRIC DOSES FROM CHEST CT EXAMINATIONS USING VIRTUALDOSE SOFTWARE"],"prefix":"10.1093","volume":"199","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6338-5484","authenticated-orcid":false,"given":"Zirui","family":"Ye","sequence":"first","affiliation":[{"name":"University of Science and Technology of China School of Nuclear Science and Technology, , Hefei 230026 , China"},{"name":"Institute of Nuclear Medical Physics, University of Science and Technology of China , Hefei 230026 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miao","family":"Qi","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China School of Nuclear Science and Technology, , Hefei 230026 , China"},{"name":"Institute of Nuclear Medical Physics, University of Science and Technology of China , Hefei 230026 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingming","family":"Zhao","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine,\u00a0University of Science and Technology of China Department of Radiology, , Hefei 230001 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wei","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine,\u00a0University of Science and Technology of China Department of Radiology, , Hefei 230001 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"X George","family":"Xu","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China School of Nuclear Science and Technology, , Hefei 230026 , China"},{"name":"Institute of Nuclear Medical Physics, University of Science and Technology of China , Hefei 230026 , China"},{"name":"The First Affiliated Hospital of USTC, University of Science and Technology of China Department of Radiation Oncology, , Hefei 230001 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,11,14]]},"reference":[{"issue":"10223","key":"2023020113425671100_ref1","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1016\/S0140-6736(20)30183-5","article-title":"Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China","volume":"395","author":"Huang","year":"2020","journal-title":"Lancet"},{"issue":"6","key":"2023020113425671100_ref2","doi-asserted-by":"crossref","first-page":"521","DOI":"10.1016\/j.ajog.2020.03.021","article-title":"Coronavirus disease 2019 (COVID-19) pandemic and pregnancy","volume":"222","author":"Dashraath","year":"2020","journal-title":"Am.
