The sensitivity, FPR, and accuracy of HMCAS were recalculated.</p><p><strong>Results: </strong>HMCAS was found in 21% of the cases and a dot sign was found in 9%. The mean HMCAS sensitivity was 62% (95% CI 45-79%) and its accuracy was 86% (95% CI 79-92%) for detecting LVO. The interobserver reliability coefficient was 80% for HMCAS. Combined with clinical information, HMCAS sensitivity increased to 81% (95% CI 68-94; p = 0.041) and accuracy increased to 91% (95% CI 86-96%).</p><p><strong>Conclusion: </strong>When clinical data are provided, detection of HMCAS on thinly sliced NCCT could be enough to decide on transfer for thrombectomy in drip-and-ship models of acute stroke management, especially in situations where CTA is less available and referral centers for thrombectomy fewer and further apart.</p>","PeriodicalId":45709,"journal":{"name":"Cerebrovascular Diseases Extra","volume":"10 1","pages":"36-43"},"PeriodicalIF":1.9,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000506971","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37880380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
