Two hundred and fourteen patients with primary hyperparathyroidism were included in the study with a two-phase CT scan between 2008 and 2020 by using a Toshiba Aquilion Prime 80 and a GE Light Speed 16. The standard \u2018neck\u2019 or a modified \u2018parathyroid\u2019 protocol was used. The patient dose was evaluated in terms of volumetric computed tomography dose index (CTDIvol), dose length product (DLP) and effective dose (ED) per acquisition protocol and CT system. CTDIvol and DLP were recorded retrospectively, while the ED was calculated based on DLP and an appropriate conversion coefficient. Comparisons of patient dose between the two protocols and two CT systems and the corresponding published values were established. A significantly lower patient dose (40.2\u201343.2%) than the GE system (p\u00a0&amp;lt;\u00a00.0001) resulted from the Toshiba system. The \u2018parathyroid\u2019 protocol resulted in a 6.5\u20139.6% lower patient dose than the standard \u2018neck\u2019 protocol. Compared with the literature, the lowest ED value (3.6\u00a0mSv) was observed since this protocol consists of a lowered tube voltage of 100 kVp, a reduced scan length for the pre-contrast phase and implementation of an iterative reconstruction algorithm.<\/jats:p>","DOI":"10.1093\/rpd\/ncab137","type":"journal-article","created":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T07:22:02Z","timestamp":1631085722000},"page":"207-219","source":"Crossref","is-referenced-by-count":6,"title":["DOSIMETRIC EVALUATION OF THE TWO-PHASE COMPUTED TOMOGRAPHY IN PARATHYROID GLANDS IMAGING"],"prefix":"10.1093","volume":"196","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6009-4059","authenticated-orcid":false,"given":"Christos P","family":"Dimitroukas","sequence":"first","affiliation":[{"name":"Department of Medical Physics, School of Medicine, University of Patras, Patras 265 04, Greece"},{"name":"Department of Medical Physics, University Hospital of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasileios I","family":"Metaxas","sequence":"additional","affiliation":[{"name":"Department of Medical Physics, School of Medicine, University of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fotios O","family":"Efthymiou","sequence":"additional","affiliation":[{"name":"Department of Medical Physics, School of Medicine, University of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petros E","family":"Zampakis","sequence":"additional","affiliation":[{"name":"Department of Radiology, School of Medicine, University of Patras, Patras 265 04, Greece"},{"name":"Department of Radiology, University Hospital of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina P","family":"Kalogeropoulou","sequence":"additional","affiliation":[{"name":"Department of Radiology, School of Medicine, University of Patras, Patras 265 04, Greece"},{"name":"Department of Radiology, University Hospital of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4802-666X","authenticated-orcid":false,"given":"George S","family":"Panayiotakis","sequence":"additional","affiliation":[{"name":"Department of Medical Physics, School of Medicine, University of Patras, Patras 265 04, Greece"},{"name":"Department of Medical Physics, University Hospital of Patras, Patras 265 04, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"key":"2021111723101041300_ref1","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1016\/j.amjoto.2011.10.010","article-title":"Imaging techniques in parathyroid surgery for primary hyperparathyroidism","volume":"33","author":"Mohebati","year":"2012","journal-title":"Am.
