Contrast-enhanced multi-shot echo-planar FLAIR (Ms-EPI-FLAIR (+)), comprising combined sequences of f-FLAIR (+) and Ms-EPI, may provide the advantages of f-FLAIR (+) along with rapid acquisition.<\/jats:p>\n                  <jats:p>Purpose: To compare Ms-EPI-FLAIR (+) with post-contrast spin-echo T1-weighted imaging (SE-T1WI (+)) in the depiction of brain metastases.<\/jats:p>\n                  <jats:p>Material and Methods: In 14 patients with metastatic tumors of the brain, spin-echo precontrast T1-weighted imaging (SE-T1WI (\u2212)), fast spin-echo T2-weighted imaging (FSE-T2WI), fast-FLAIR, SE-T1WI (+), and Ms-EPI-FLAIR (+) were acquired. For qualitative evaluation of SE-T1WI (+) and Ms-EPI-FLAIR (+), receiver operating characteristic (ROC) analysis was performed in two different readers. For quantitative analysis, the intensity ratios (intensity of tumor divided by intensity of peritumoral region) in SE-T1WI (+) and Ms-EPI-FLAIR (+) were compared.<\/jats:p>\n                  <jats:p>Results: Although pre-contrast f-FLAIR detected 84 of 106 tumors, Ms-EPI-FLAIR (+) detected 98 of 106 tumors. In the ROC analysis for observers A and B, Az values in SE-T1WI (+) did not differ from values in Ms-EPI-FLAIR (+). Quantitatively, the intensity ratio in Ms-EPI-FLAIR (+) also did not differ from that in SE-T1WI (+).<\/jats:p>\n                  <jats:p>Conclusion: Detectability of brain metastases with Ms-EPI-FLAIR (+) is almost similar to that with SE-T1WI (+). Ms-EPI-FLAIR (+) could be an alternative to SE-T1WI (+) in the depiction of brain metastases.<\/jats:p>","DOI":"10.1080\/02841850701499425","type":"journal-article","created":{"date-parts":[[2007,10,25]],"date-time":"2007-10-25T02:30:06Z","timestamp":1193279406000},"page":"1032-1037","source":"Crossref","is-referenced-by-count":14,"title":["Contrast-enhanced multi-shot echo-planar FLAIR in the depiction of metastatic tumors of the brain: comparison with contrast-enhanced spin-echo T1-weighted imaging"],"prefix":"10.1177","volume":"48","author":[{"given":"N.","family":"Tomura","sequence":"first","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Narita","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Otani","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Nishii","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Watarai","sequence":"additional","affiliation":[{"name":"Department of Radiology, Akita University School of Medicine, Akita, 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\/02841850701499425","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850701499425","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:50:42Z","timestamp":1777384242000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/02841850701499425"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,11]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2007,11]]}},"alternative-id":["10.1080\/02841850701499425"],"URL":"https:\/\/doi.org\/10.1080\/02841850701499425","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,11]]}}}
