Patients with recent subarachnoid hemorrhage underwent color \u201cpower\u201d TCD blind to angiography. Identified aneurysms were measured from the frozen image (in real time or from video tape) using the trackball function. Two observers measured the maximum (systolic) and mininum (end diastolic) area of each aneurysm, and an adjacent reference artery. Each observer was blind to the other's results. lnterobserver variability was assessed using the Bland and Altman technique. Thirty\u2010nine aneurysms were identified in 32 patients in 10 months. The maximum cross\u2010sectional area of the aneurysm was 38:41 mm<jats:sup>2<\/jats:sup> (observer 1 :observer 2), and the mean difference was \u20133 mm<jats:sup>2<\/jats:sup> (95% confidence interval [CI] of the difference \u2013 5.4\u20131 .46 mm<jats:sup>2<\/jats:sup>).The maximum cross\u2010sectional area of the reference artery was 26:28 mm<jats:sup>2<\/jats:sup> (observer 1 : observer 2), and the mean difference was \u20132 mm<jats:sup>2<\/jats:sup> (95% Cl \u20135.7\u20131.2 mm<jats:sup>2<\/jats:sup> ) Neither difference was significant. lntraobserver reliability also was good. The measurement of intracranial aneurysm and artery size with power TCD is reliable sufficiently for use in longitudinal studies of changes in aneurysm size.<\/jats:p>","DOI":"10.1111\/jon19988275","type":"journal-article","created":{"date-parts":[[2016,2,8]],"date-time":"2016-02-08T10:18:48Z","timestamp":1454926728000},"page":"75-77","source":"Crossref","is-referenced-by-count":2,"title":["Observer Variability in the Measurement of the Size of Intracranial Aneurysms Using Power TCD"],"prefix":"10.1111","volume":"8","author":[{"given":"Juliet","family":"Percival","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna Marguerite","family":"Wardlaw","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Cannon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,2,4]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"51","volume-title":"Transcranial color-coded real-time ultrasonography in adults","author":"Becker G","year":"1993"},{"key":"e_1_2_1_3_1","doi-asserted-by":"crossref","first-page":"420","DOI":"10.1227\/00006123-199209000-00006","article-title":"Transcranial colorcoded real-time sonography in the evaluation of intracranial neoplasms and arteriovenous malformations","volume":"31","author":"Becker G","year":"1992","journal-title":"Neurosurgery"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0301-5629(91)90179-Z"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1996.84.3.0459"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90837-8"}],"container-title":["Journal of Neuroimaging"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjon19988275","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjon19988275","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jon19988275","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,28]],"date-time":"2023-10-28T13:22:07Z","timestamp":1698499327000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jon19988275"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,4]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1998,4]]}},"alternative-id":["10.1111\/jon19988275"],"URL":"https:\/\/doi.org\/10.1111\/jon19988275","archive":["Portico"],"relation":{},"ISSN":["1051-2284","1552-6569"],"issn-type":[{"value":"1051-2284","type":"print"},{"value":"1552-6569","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,4]]}}}
