This prospective study investigated the impact of gantry tilt on organ doses using thermoluminescent dosemeters. A total of 67 pediatric patients undergoing brain CT were divided into four age groups: 0\u201318\u00a0months, 18\u00a0months\u20135\u00a0y, 5\u201310\u00a0y, and 10\u201317\u00a0y. In vivo lens and thyroid doses were measured with and without gantry tilt, and their correlation with volume CT dose index (CTDIvol) was assessed. Significant positive correlations were observed between CTDIvol and both lens and thyroid doses. With gantry tilt, mean lens doses were 2.19\u20135.73\u00a0mGy and thyroid doses 0.68\u20130.99\u00a0mGy, compared with 10.89\u201329.30\u00a0mGy and 1.29\u20133.72\u00a0mGy, respectively, without tilt. Gantry tilt parallel to the supraorbital\u2013meatal baseline substantially reduced organ doses, particularly to the lens, and should be considered as a practical optimisation technique in pediatric neuroimaging.<\/jats:p>","DOI":"10.1093\/rpd\/ncaf144","type":"journal-article","created":{"date-parts":[[2025,11,21]],"date-time":"2025-11-21T15:19:06Z","timestamp":1763738346000},"page":"8-14","source":"Crossref","is-referenced-by-count":1,"title":["Gantry tilt as a dose reduction strategy for radiosensitive organs in pediatric brain CT: a prospective TLD study"],"prefix":"10.1093","volume":"202","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6773-3132","authenticated-orcid":false,"given":"Osman Vefa","family":"Gul","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Faculty of Medicine, Selcuk University , Konya 42130 ,","place":["Turkey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Koplay","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Selcuk University , Konya, 42130 ,","place":["Turkey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet","family":"Ozturk","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Selcuk University , Konya, 42130 ,","place":["Turkey"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,11,21]]},"reference":[{"key":"2026010207212626100_ref1","doi-asserted-by":"publisher","first-page":"544","DOI":"10.1016\/j.precisioneng.2019.06.007","article-title":"X-ray computed tomography: from medical imaging to dimensional metrology","volume":"60","author":"Villarraga-G\u00f3mez","year":"2019","journal-title":"Precis Eng"},{"key":"2026010207212626100_ref2","doi-asserted-by":"publisher","first-page":"163","DOI":"10.1016\/B978-0-12-824086-1.00011-6","volume-title":"Applications of Multi-Criteria Decision-Making Theories in Healthcare and Biomedical Engineering","author":"Mustapha","year":"2021"},{"key":"2026010207212626100_ref3","doi-asserted-by":"publisher","first-page":"302","DOI":"10.1093\/rpd\/ncx010","article-title":"Establishment of radiation doses for Pediatric X-ray examinations in a large Pediatric Hospital in Turkey","volume":"176","author":"Olgar","year":"2017","journal-title":"Radiat Prot Dosim"},{"key":"2026010207212626100_ref4","doi-asserted-by":"publisher","volume":"216","journal-title":"Progres dans les recherches sur le cancer","DOI":"10.1007\/978-3-030-42618-7_1"},{"key":"2026010207212626100_ref5","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-021-21232-1","article-title":"High-speed three-dimensional photoacoustic computed tomography for preclinical research and clinical translation","volume":"12","author":"Lin","year":"2021","journal-title":"Nat Commun"},{"key":"2026010207212626100_ref6","doi-asserted-by":"publisher","DOI":"10.1002\/btm2.10419","article-title":"Application of photoacoustic computed tomography in biomedical imaging: a literature review","volume":"8","author":"Gu","year":"2022","journal-title":"Bioeng Translational Med"},{"key":"2026010207212626100_ref7","doi-asserted-by":"publisher","first-page":"619","DOI":"10.1148\/radiol.2303021726","article-title":"Strategies for CT radiation dose optimization","volume":"230","author":"Kalra","year":"2004","journal-title":"Radiology"},{"key":"2026010207212626100_ref8","doi-asserted-by":"publisher","first-page":"418","DOI":"10.1148\/radiol.2020192256","article-title":"Patient exposure from radiologic and nuclear medicine procedures in the United States: procedure volume and effective dose for the period 2006\u20132016","volume":"295","author":"Mettler","year":"2020","journal-title":"Radiology"},{"key":"2026010207212626100_ref9","doi-asserted-by":"publisher","first-page":"2493","DOI":"10.1007\/s00330-019-06528-7","article-title":"Multinational data on cumulative radiation exposure of patients from recurrent radiological procedures: call for action","volume":"30","author":"Brambilla","year":"2019","journal-title":"Eur Radiol"},{"key":"2026010207212626100_ref10","doi-asserted-by":"publisher","first-page":"346","DOI":"10.1080\/10520295.2023.2189752","article-title":"Effect of melatonin on low and high dose radiotherapy induced thyroid injury","volume":"98","author":"Aras","year":"2023","journal-title":"Biotech Histochem"},{"key":"2026010207212626100_ref11","doi-asserted-by":"publisher","first-page":"1282","DOI":"10.1080\/09553002.2021.1931527","article-title":"Lifetime attributable cancer risk related to prevalent CT scan procedures in pediatric medical imaging centers","volume":"97","author":"Tahmasebzadeh","year":"2021","journal-title":"Int J Radiat Biol"},{"key":"2026010207212626100_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2021.103292","article-title":"How much is too much?
