MR imaging depicted lingual thyroid in the midline in the base of the tongue (n=5) and additional ectopic thyroid glands in the floor of the mouth (n=2) or between the right and left sternohyoid muscles (n=1). Ectopic thyroid glands appeared isointense or hyperintense relative to muscle tissue on T1-weighted images and showed slight or fair contrast enhancement. All glands had low to intermediate T2 signal, which was also seen in 1 case of non-Hodgkin's lymphoma and 1 case of adenoid cystic carcinoma. All ectopic thyroid glands had well-defined margins, whereas malignant tumors tended to have ill-defined margins and to invade the surrounding structures. All but the 5 cases of lingual thyroid had an MR-demonstrable thyroid gland in the normal cervical position.<\/jats:p>\n                  <jats:p>Conclusion: A well-defined mass of low-intermediate T2 signal in the midline base of the tongue, neither with invasive tendency nor with a cervical thyroid gland in the normal site on MR imaging, may strongly indicate lingual thyroid.<\/jats:p>","DOI":"10.1080\/028418501127347016","type":"journal-article","created":{"date-parts":[[2004,7,23]],"date-time":"2004-07-23T15:10:35Z","timestamp":1090595435000},"page":"376-382","source":"Crossref","is-referenced-by-count":3,"title":["MR imaging of the lingual thyroid: Comparison to other submucosal lesions"],"prefix":"10.1177","volume":"42","author":[{"given":"S.","family":"Takashima","sequence":"first","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Ueda","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Shibata","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Takayama","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Momose","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Yamashita","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shinshu University School of Medicine, Matsumoto, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,8,30]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/028418501127347016","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/028418501127347016","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:45:23Z","timestamp":1777383923000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/028418501127347016"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,7]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2001,7]]}},"alternative-id":["10.1080\/028418501127347016"],"URL":"https:\/\/doi.org\/10.1080\/028418501127347016","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,7]]}}}
