Other infundibular lesions, including adenohypophysitis (n=3), Langerhans' cell histiocytosis (LCH, n=2), and 1 hemangioblastoma from von Hippel-Lindau disease, were also evaluated. Serial images were obtained every 15 s (turbo SE) or 30 s (SE technique) for 240 s after rapid injection of contrast medium. The dynamic patterns were analyzed quantitatively with the contrast medium enhancement ratio.<\/jats:p>\n                  <jats:p>Results: On dynamic MR images, GCTs typically showed a gradual enhancement increase with a peak between 105 s and 180 s, while two showed a relatively rapid increase. LCH and hemangioblastoma showed a dynamic pattern similar to GCTs, while adenohypophysitis demonstrated a sharp rise and a steeper wash-out with an obvious peak before 90 s.<\/jats:p>\n                  <jats:p>Conclusion: Typical dynamic pattern of GCTs was the gradual enhancement increase without wash-out. Dynamic MR imaging can distinguish GCTs from adenohypophysitis, but is not useful for differentiation from LCH.<\/jats:p>","DOI":"10.1080\/028418500127345901","type":"journal-article","created":{"date-parts":[[2004,7,23]],"date-time":"2004-07-23T15:10:35Z","timestamp":1090595435000},"page":"562-566","source":"Crossref","is-referenced-by-count":13,"title":["Dynamic MR imaging of neurohypophyseal germ cell tumors for differential diagnosis of infundibular diseases"],"prefix":"10.1177","volume":"41","author":[{"given":"L.","family":"Liang","sequence":"first","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Korogi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Sugahara","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Ikushima","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Shigematsu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Okuda","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kumamoto University School of Medicine, Kumamoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"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\/028418500127345901","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/028418500127345901","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:45:02Z","timestamp":1777383902000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/028418500127345901"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,11]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2000,11]]}},"alternative-id":["10.1080\/028418500127345901"],"URL":"https:\/\/doi.org\/10.1080\/028418500127345901","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,11]]}}}
