In 2017, American Association of Physicists in Medicine recommended against Bi shielding due to its degrading effects on image quality. Saba shielding introduced recently protecting organs as Bi shielding without degrading image quality. In this study, the Saba shield was modified and primary radiation attenuation values of the shields and entrance skin dose (ESD) on the thyroid were measured with and without shielding. Furthermore, the quality of images obtained using Saba shielding was investigated quantitatively and qualitatively. Saba and Bi shielding reduced the ESD on the thyroid by about 50%. Saba shielding had about 5\u20137\u2009HU less noise and about 51\u201365\u2009HU less CT numbers shift in comparison with Bi shielding at a distance of 1\u00a0cm from the shields. Saba shielding had no degrading effects on image quality in the patient study.<\/jats:p>","DOI":"10.1093\/rpd\/ncaa153","type":"journal-article","created":{"date-parts":[[2020,9,24]],"date-time":"2020-09-24T11:24:14Z","timestamp":1600946654000},"page":"349-360","source":"Crossref","is-referenced-by-count":6,"title":["REDUCING ABSORBED DOSE TO THYROID IN NECK CT EXAMINATIONS: THE EFFECTS OF SABA SHIELDING"],"prefix":"10.1093","volume":"191","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5531-5171","authenticated-orcid":false,"given":"Valiallah","family":"Saba","sequence":"first","affiliation":[{"name":"Faculty of Paramedicine, Radiology Department, Aja University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jalal Kargar","family":"Shuraki","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Radiology Department, Aja University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdollah","family":"Valizadeh","sequence":"additional","affiliation":[{"name":"Faculty of Paramedicine, Radiology Department, Aja University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohsen","family":"Zahedinia","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Radiology Department, Aja University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maziar","family":"Barkhordari","sequence":"additional","affiliation":[{"name":"Faculty of Paramedicine, Radiology Department, Aja University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,10,30]]},"reference":[{"issue":"3","key":"2020120402371653500_ref1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1148\/radiology.205.3.9393547","article-title":"The breast: in-plane x-ray protection during diagnostic thoracic CT-shielding with bismuth radioprotective garments","volume":"205","author":"Hopper","year":"1997","journal-title":"Radiology"},{"issue":"6","key":"2020120402371653500_ref2","first-page":"1194","article-title":"Radioprotection to the eye during CT scanning","volume":"22","author":"Hopper","year":"2001","journal-title":"Am.
