The usefulness of a novel cone-beam CT device in CI recipient\u2019s inner ear imaging was evaluated and the exposure parameters were optimised to attain adequate clinical image quality at the lowest effective dose (ED). Six temporal bones were implanted with a Cochlear Slim Straight electrode array and imaged with six different imaging protocols. Contrast-to-noise ratio was calculated for each imaging protocol, and three observers evaluated independently the image quality of each imaging protocol and temporal bone. The overall image quality of the inner ear structures did not differ between the imaging protocols and the most relevant inner ear structures of CI recipient\u2019s inner ear can be visualised with a low ED. To visualise the most delicate structures in the inner ear, imaging protocols with higher radiation exposure may be required.<\/jats:p>","DOI":"10.1093\/rpd\/ncad019","type":"journal-article","created":{"date-parts":[[2023,2,15]],"date-time":"2023-02-15T10:18:04Z","timestamp":1676456284000},"page":"462-470","source":"Crossref","is-referenced-by-count":3,"title":["OPTIMISING THE PARAMETERS OF COCHLEAR IMPLANT IMAGING WITH CONE-BEAM COMPUTED TOMOGRAPHY"],"prefix":"10.1093","volume":"199","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6256-4598","authenticated-orcid":false,"given":"Samuel","family":"S\u00f6derqvist","sequence":"first","affiliation":[{"name":"Helsinki University Hospital and University of Helsinki Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"},{"name":"Helsinki University Hospital Tauno Palva Laboratory, Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ville","family":"Sivonen","sequence":"additional","affiliation":[{"name":"Helsinki University Hospital and University of Helsinki Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antti","family":"Aarnisalo","sequence":"additional","affiliation":[{"name":"Helsinki University Hospital and University of Helsinki Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harri","family":"Karppi","sequence":"additional","affiliation":[{"name":"Planmeca Oy , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saku T","family":"Sinkkonen","sequence":"additional","affiliation":[{"name":"Helsinki University Hospital and University of Helsinki Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"},{"name":"Helsinki University Hospital Tauno Palva Laboratory, Department of Otorhinolaryngology\u2014Head and Neck Surgery, Head and Neck Center, , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juha","family":"Koivisto","sequence":"additional","affiliation":[{"name":"University of Helsinki Department of Physics, , Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,2,13]]},"reference":[{"issue":"1","key":"2023040610561890500_","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1177\/0194599813510862","article-title":"Intraoperative cone-beam computed tomography and multi-slice computed tomography in temporal bone imaging for surgical treatment","volume":"150","author":"Erovic","year":"2014","journal-title":"Otolaryngol.
