All patients received US and magnetic resonance imaging (MRI) of both TMJs 1 to 5 days after the clinical\u00a0examination. MRI examinations were performed using 1.5 T MRI equipment (Siemens Avanto, Siemens, Erlangen). Ultrasonographic\u00a0examination was performed on a Hitachi EUB 8500 (Hitachi Medical Corp., Tokyo, Japan) scanner with L 54 M6.5-13 MHz linear transducer.Results: MRI depicted 68 (45.95%) normal joints, 47 (31.76%) with disc displacement with\u00a0reduction, 33 (22.3%) with disc displacement without reduction and 34 (22.97%) with degenerative changes. US detected 78\u00a0(52.7%) normal joints, 37 (25%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction\u00a0and 21 (14.19%) with degenerative changes. Compared to MRI, US showed a sensitivity of 93.1%, specificity of 87.88%,\u00a0accuracy of 90.32%, a positive predictive value of 87.1% and a negative predictive value of 93.55% for overall diagnosis of\u00a0disc displacement. The Youden index was 0.81.Conclusions: Based on our results, high-resolution ultrasonography showed high sensitivity, specificity and accuracy in the diagnosis of TMJ disc displacement. It could be a valuable imaging technique\u00a0in assessing TMJ disc position. The diagnostic value of high-resolution ultrasonography depends strictly on the examiner\u2019s\u00a0skills and on the equipment used.\u00a0<\/jats:p>","DOI":"10.11152\/mu-1025","type":"journal-article","created":{"date-parts":[[2017,8,29]],"date-time":"2017-08-29T15:32:13Z","timestamp":1504020733000},"page":"64","source":"Crossref","is-referenced-by-count":18,"title":["High-resolution ultrasonography in assessing temporomandibular joint disc position"],"prefix":"10.11152","volume":"1","author":[{"given":"Daniel","family":"Talmaceanu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lavinia Manuela","family":"Lenghel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolae","family":"Bolog","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roxana","family":"Popa Stanila","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Smaranda","family":"Buduru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel Corneliu","family":"Leucuta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Horatiu","family":"Rotar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihaela","family":"Baciut","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grigore","family":"Baciut","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4840","published-online":{"date-parts":[[2018,2,4]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1025\/1111","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1025\/1111","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,2,4]],"date-time":"2018-02-04T10:19:59Z","timestamp":1517739599000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/1025"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,4]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,2,4]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-1025","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2018,2,4]]}}}
