This study evaluates the robustness and safety of a low-dose protocol on a\u00a0CT scanner with iterative reconstruction software.<\/jats:p><jats:p>\n            Materials and Methods\u2002A total of 183 patients who underwent periradicular infiltration therapy of the cervical spine were included in this study. 82 interventions were performed on a new CT scanner with a new intervention protocol using an iterative reconstruction algorithm. Spot scanning was implemented for planning and a basic low-dose setup of 80 kVp and 5\u200amAs was established during intermittent fluoroscopy. The comparison group included 101 prior interventions on a scanner without iterative reconstruction. The dose-length product (DLP), number of acquisitions, pain reduction on a numeric analog scale, and protocol changes to achieve a safe intervention were recorded.<\/jats:p><jats:p>\n            Results\u2002The median DLP for the whole intervention was 24.3 mGy*cm in the comparison group and 1.8 mGy*cm in the study group.\u200aThe median pain reduction was \u20133 in the study group and \u20132 in the comparison group.\u200aA 5\u200amAs increase in the tube current-time product was required in 5 patients of the study group.<\/jats:p><jats:p>\n            Conclusion\u2002Implementation of a new scanner and intervention protocol resulted in a 92.6\u200a% dose reduction without a compromise in safety and pain relief. The dose needed here is more than 75\u200a% lower than doses used for similar interventions in published studies. An increase of the tube current-time product was needed in only 6\u200a% of interventions.<\/jats:p><jats:p>\n            Key Points:\u2002<\/jats:p><jats:p>\n            Citation Format\n          <\/jats:p>","DOI":"10.1055\/a-0632-3930","type":"journal-article","created":{"date-parts":[[2018,6,18]],"date-time":"2018-06-18T19:05:56Z","timestamp":1529348756000},"page":"54-61","source":"Crossref","is-referenced-by-count":3,"title":["Periradicular Infiltration of the Cervical Spine: How New CT Scanner\u00a0Techniques and Protocol Modifications Contribute to the Achievement of Low-Dose Interventions"],"prefix":"10.1055","volume":"191","author":[{"given":"Fabian","family":"Elsholtz","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Campus Benjamin Franklin, Charit\u00e9- Universit\u00e4tsmedizin Berlin, corporate member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Kamp","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Campus Benjamin Franklin, Charit\u00e9- Universit\u00e4tsmedizin Berlin, corporate member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janis","family":"Vahldiek","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Campus Benjamin Franklin, Charit\u00e9- Universit\u00e4tsmedizin Berlin, corporate member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Hamm","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Campus Benjamin Franklin, Charit\u00e9- Universit\u00e4tsmedizin Berlin, corporate member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Niehues","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Campus Benjamin Franklin, Charit\u00e9- Universit\u00e4tsmedizin Berlin, corporate member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,6,18]]},"container-title":["R\u00f6Fo - Fortschritte auf dem Gebiet der R\u00f6ntgenstrahlen und der bildgebenden Verfahren"],"original-title":[],"language":"de","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0632-3930.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,2,4]],"date-time":"2019-02-04T05:12:24Z","timestamp":1549257144000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0632-3930"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,6,18]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2018,12,13]]},"published-print":{"date-parts":[[2019,1]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0632-3930","relation":{},"ISSN":["1438-9029","1438-9010"],"issn-type":[{"value":"1438-9029","type":"print"},{"value":"1438-9010","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,6,18]]}}}
