This requires additional anesthesia for the patient. Recently, intraoperative mobile cone-beam CT (CBCT) devices have gained popularity for orthopedic and neurosurgical procedures, which allows postoperative CT imaging in the operating room.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Objective<\/jats:title>\n                <jats:p>This single-center retrospective study compared radiation dose and image quality of postoperative imaging performed using conventional MSCT scanners and O-arm CBCT.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>A total of\u00a0104 pediatric syndromic and non-syndromic patients who were operated on\u00a0because of single- or multiple-suture craniosynostosis were included in this study. The mean volumetric CT dose index (CTDI<jats:sub>vol<\/jats:sub>) and dose-length product (DLP) values of optimized craniosynostosis CT examinations (58 MSCT and 46 CBCT) were compared. Two surgeons evaluated the subjective image quality.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>CBCT resulted in significantly lower CTDI<jats:sub>vol<\/jats:sub> (up to 14%) and DLP (up to 33%) compared to MSCT. Multi-slice\u00a0CT image quality was considered superior to CBCT scans. However, all scans were considered to be of\u00a0sufficient\u00a0quality\u00a0for diagnosis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The O-arm device allowed for an immediate postoperative CBCT examination in the operating theater using the same anesthesia induction. Radiation exposure was lower in CBCT compared to MSCT scans, thus further encouraging the use of O-arms. Cone-beam\u00a0CT imaging with an O-arm is a feasible method for postoperative craniosynostosis imaging, yielding less anesthesia to patients, lower health costs and the possibility to immediately\u00a0evaluate results\u00a0of the surgical operation.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00247-023-05644-3","type":"journal-article","created":{"date-parts":[[2023,3,27]],"date-time":"2023-03-27T03:51:47Z","timestamp":1679889107000},"page":"1704-1712","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Postoperative computed tomography imaging of pediatric patients with\u00a0craniosynostosis: radiation dose and image quality comparison between multi-slice computed tomography and O-arm cone-beam computed tomography"],"prefix":"10.1007","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5391-2666","authenticated-orcid":false,"given":"Touko","family":"Kaasalainen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ville","family":"M\u00e4nnist\u00f6","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teemu","family":"M\u00e4kel\u00e4","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juho","family":"Suojanen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antton","family":"Nuorala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arja","family":"Heli\u00f6vaara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junnu","family":"Leikola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,3,27]]},"reference":[{"key":"5644_CR1","doi-asserted-by":"publisher","first-page":"359","DOI":"10.1016\/j.ajhg.2015.07.006","volume":"97","author":"SR Twigg","year":"2015","unstructured":"Twigg SR, Wilkie AO (2015) A genetic-pathophysiological framework for craniosynostosis.
