This study aims to analyse the radiation exposure of chest and abdomen CT in paediatric patients following trauma resuscitation. A retrospective single-centre study was conducted on patients aged 0\u2013&lt;15 years who underwent CT in the trauma resuscitation unit between 04\/2020 and 08\/2023. Patients were categorised into three age groups (AGs) (I: 0\u2013&lt;5years, II: 5\u2013&lt;10 years, III: 10\u2013&lt;15 years) and radiation exposure parameters were analysed age-stratified. Effective dose (ED) was calculated using conversion factors and organ doses were determined through Monte Carlo simulations. Out of 212 paediatric patients, 62.7% (133\/212) received a CT scan, with 60.2% (80\/133) undergoing combined chest and abdomen CT. In 70.0% (56\/80), the standard protocol was applied, complete dose data available, and these were included in the dose calculation (median age: 6.2 years; IQR: 3.9\u201310.5 years; 37.5% female). Radiation exposure was as follows (median [IQR] CTDIvol, DLP, ED): chest: I: 0.7 mGy (0.5\u20130.8), 13 mGycm (10\u201316), 2.1 mSv (1.6\u20132.4); II: 1.4 mGy (1.1\u20131.9), 35 mGycm (25\u201349), 3.7 mSv (2.7\u20135.2); III: 2.7 mGy (2.2\u20133.2), 76 mGycm (66\u201395), 4.3 mSv (3.7\u20135.3); abdomen: I: 0.8 mGy (0.6\u20130.9), 24 mGycm (20\u201329), 2.0 mSv (1.6\u20132.5); II: 1.6 mGy (1.1\u20131.9), 60 mGycm (41\u201377), 3.2 mSv (2.2\u20134.2); III: 3.1 mGy (2.4\u20133.9), 143 mGycm (101\u2013179), 4.3 mSv (3.0\u20135.4). In the organ dose analysis, the genital organs were particularly affected by increased radiation exposure. 16.1% (9\/56) of patients were not scanned using age-adapted protocols. Chest and abdomen CT in paediatric trauma patients can be performed with moderate radiation exposure. Nonetheless, non-adherence to age-adapted protocols highlights the need for improved compliance to ensure optimal radiation safety in paediatric trauma imaging.<\/jats:p>","DOI":"10.1088\/1361-6498\/ae0a5a","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T22:47:51Z","timestamp":1758667671000},"page":"041505","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Radiation exposure of chest and abdomen computed tomography in paediatric trauma patients"],"prefix":"10.1088","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2776-6604","authenticated-orcid":true,"given":"Daniel","family":"Rosok","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7455-8590","authenticated-orcid":true,"given":"Marcel","family":"Opitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9585-9787","authenticated-orcid":true,"given":"Denise","family":"Bos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannick","family":"Thal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Behr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcel","family":"Drews","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raya","family":"Serger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathias","family":"Holtkamp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Salh\u00f6fer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcel","family":"Dudda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Haubold","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedikt","family":"Schaarschmidt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Schweiger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lale","family":"Umutlu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Forsting","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2997-0740","authenticated-orcid":true,"given":"Sebastian","family":"Zensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2025,10,16]]},"reference":[{"key":"jrpae0a5abib1","doi-asserted-by":"publisher","first-page":"320","DOI":"10.1016\/j.annemergmed.2006.09.025","type":"journal-article","article-title":"Pediatric head trauma: changes in use of computed tomography in emergency departments in the United States over time","volume":"49","author":"Blackwell","year":"2007","journal-title":"Ann.
