Ultrasound measurements for common carotid artery (CCA) and ICA were as follows: flow volume (FV), peak systolic velocity (PSV), end-diastolic velocity (EDV), pulsatility index (PI) and resistance index (RI). The sensitivity and specificity of the ultrasound criteria for determining intracranial ICA or MCA \u226750% stenosis were calculated. &lt;i&gt;Results:&lt;\/i&gt; The criteria identified for detecting intracranial ICA \u226750% stenosis were ICA FV &lt;159 ml\/min, ICA PSV &lt;33 cm\/s and CCA PSV &lt;42 cm\/s. When ICA PSV &lt;33 cm\/s was combined with CCA PSV &lt;42 cm\/s, sensitivity increased to 82%, with 91% specificity. The criteria identified for detecting MCA \u226750% stenosis were CCA FV &lt;285 ml\/min, ICA FV &lt;179 ml\/min, ICA PSV &lt;33 cm\/s, &gt;35% reduction in FV in the CCA, &gt;40% reduction in FV in ICA, and &gt;35% reduction in PSV in ICA. When these criteria were combined, sensitivity increased to 69%, with 85% specificity. &lt;i&gt;Conclusion:&lt;\/i&gt; This study demonstrated that ultrasound criteria are sensitive and specific for detecting intracranial ICA and MCA significant obstruction.<\/jats:p>","DOI":"10.1159\/000098467","type":"journal-article","created":{"date-parts":[[2007,1,11]],"date-time":"2007-01-11T15:36:00Z","timestamp":1168529760000},"page":"156-160","source":"Crossref","is-referenced-by-count":9,"title":["Carotid Ultrasound Criteria for Detecting Intracranial Carotid Stenosis"],"prefix":"10.1159","volume":"57","author":[{"given":"Jiann-Der","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shan-Jin","family":"Ryu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeu-Jhy","family":"Chang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai-Cheng","family":"Hsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Chun","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying-Chih","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming-Chang","family":"Hsiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsong-Hai","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2007,1,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097%2F00000658-198803000-00015"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1177%2F000331978503600103"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1067%2Fmva.1987.avs0050551"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1067%2Fmva.1989.vs0090074"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2F0301-5629%2896%2900032-4"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.56.9.967"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1177%2F000331979304400803"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000080698"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jvs.2004.08.030"}],"container-title":["European Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/98467","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/98467","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:32:02Z","timestamp":1745461922000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000098467"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":9,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2007,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000098467","archive":["Portico"],"relation":{},"ISSN":["0014-3022","1421-9913"],"issn-type":[{"value":"0014-3022","type":"print"},{"value":"1421-9913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
