However, the relationship between the signs is not fully known. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; Patients suspected of having hyperacute (&lt;3 h from symptom onset) stroke were prospectively enrolled. MRI including T2* and MR angiography, and thin-section CT were performed on admission. The consistency between SVS and HMCAS were evaluated. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; A total of 67 patients [38 males, median age: 76 (interquartile range: 67\u201382) years, median NIHSS score: 12 (4\u201321)] were enrolled. SVS was observed in 6 patients (9%), and HMCAS was present in 8 (12%). Sixteen patients (24%) had middle cerebral artery proximal (M1) occlusion on MR angiography. The presence or absence of SVS was highly consistent with that of HMCAS when all cases were evaluated (\u0138 = 0.841), as well as when only patients with M1 occlusion were assessed (\u0138 = 0.750). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; SVS and HMCAS were highly consistent with each other in suspected hyperacute stroke patients. SVS and HMCAS may represent the same thrombus.<\/jats:p>","DOI":"10.1159\/000338308","type":"journal-article","created":{"date-parts":[[2012,7,3]],"date-time":"2012-07-03T15:29:28Z","timestamp":1341329368000},"page":"93-97","source":"Crossref","is-referenced-by-count":16,"title":["M1 Susceptibility Vessel Sign and Hyperdense Middle Cerebral Artery Sign in Hyperacute Stroke Patients"],"prefix":"10.1159","volume":"68","author":[{"given":"Yuki","family":"Sakamoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazumi","family":"Kimura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichiro","family":"Sakai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2012,7,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1148%2Fradiol.2322030273"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000185932.73486.7a"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1161%2FSTROKEAHA.109.552588"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00588219"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.14.5.756"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159%2F000256648"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.2214%2FAJR.05.0447"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.2008.150185"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1159%2F000319071"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000185720.03803.41"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1161%2FSTROKEAHA.110.605576"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.24.1.35"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.23.3.317"}],"container-title":["European Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/338308","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/338308","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/338308","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:18:18Z","timestamp":1745432298000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000338308"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":13,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2012,8,1]]},"published-print":{"date-parts":[[2012,8,21]]}},"URL":"https:\/\/doi.org\/10.1159\/000338308","archive":["Portico"],"relation":{},"ISSN":["0014-3022","1421-9913"],"issn-type":[{"value":"0014-3022","type":"print"},{"value":"1421-9913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
