Angiography documented a total of 21 vertebral artery lesions (16 stenoses and 5 occlusions), with 7 of 10 patients having multiple sites of vertebral artery dissection. Vertebral Doppler was abnormal in 8 of the 10 patients. A high resistance signal in the relevant vertebral artery was found in 6 patients, no flow in a well-imaged vertebral artery in 1, and bilateral retrograde vertebral artery flow in 1 patient. Transcranial Doppler was abnormal in only 2 patients, with reduced pulsatility index in 1 and high resistance vertebral signal in another. A hyperintense intramural signal of the affected vertebral artery by magnetic resonance imaging was documented in 1 patient in whom Doppler sonography was nondiagnostic.<\/jats:p>\n          <jats:p>Vertebral artery dissection can be detected and monitored by noninvasive vertebral Doppler and magnetic resonance imaging in the setting of a clinically suggestive presentation.<\/jats:p>","DOI":"10.1161\/01.str.24.6.815","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:10:52Z","timestamp":1308341452000},"page":"815-819","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":50,"title":["Noninvasive detection of vertebral artery dissection."],"prefix":"10.1161","volume":"24","author":[{"given":"M","family":"Hoffmann","sequence":"first","affiliation":[{"name":"Department of Neurology, Columbia Presbyterian Medical Center, New York, NY 10032."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R L","family":"Sacco","sequence":"additional","affiliation":[{"name":"Department of Neurology, Columbia Presbyterian Medical Center, New York, NY 10032."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Neurology, Columbia Presbyterian Medical Center, New York, NY 10032."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J P","family":"Mohr","sequence":"additional","affiliation":[{"name":"Department of Neurology, Columbia Presbyterian Medical Center, New York, NY 10032."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Stroke"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.STR.24.6.815","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T22:00:47Z","timestamp":1715551247000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.STR.24.6.815"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,6]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1993,6]]}},"alternative-id":["10.1161\/01.STR.24.6.815"],"URL":"https:\/\/doi.org\/10.1161\/01.str.24.6.815","relation":{},"ISSN":["0039-2499","1524-4628"],"issn-type":[{"value":"0039-2499","type":"print"},{"value":"1524-4628","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,6]]},"assertion":[{"value":"1993-06-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
