In turn, the appearance of a sudden vessel cutoff in these vascular distributions on CTA or MRA is not always straightforward and may represent true occlusion, variant anatomy, and\/or artifact (Leary MC, Kidwell CS, Villablanca JP, et al.

Given the importance of rapidly establishing an accurate diagnosis in the setting of stroke, combined with recent clinical trials and movements promoting the efficacy of endovascular therapeutic approaches to treat MeVOs, it remains imperative to detect such occlusions accurately and quickly on imaging. In turn, we present five imaging patterns of the Sylvian Triangle on sagittal reformatted images from CTA Head examinations, which our practice has utilized to assess patency of the M2 and M3 divisions. This approach is rapidly deployable and can be utilized by radiology and non-radiology healthcare providers alike, thus facilitating rapid and accurate diagnosis of MeVO, timely evaluation of candidacy for endovascular therapy, and ultimately supporting favorable door-to-intervention time and successful patient outcomes.\n                  <\/jats:p>","DOI":"10.1177\/15910199241258373","type":"journal-article","created":{"date-parts":[[2024,6,4]],"date-time":"2024-06-04T04:04:05Z","timestamp":1717473845000},"page":"2002-2007","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Identifying the Sylvian Triangle on CT angiography: A technique for detecting distal middle cerebral artery occlusions"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3641-135X","authenticated-orcid":false,"given":"Stephen J.","family":"Sozio","sequence":"first","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Castro","sequence":"additional","affiliation":[{"name":"Cooperman Barnabas Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sri Hari","family":"Sundararajan","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Schonfeld","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaurav","family":"Gupta","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nancy C.","family":"Prendergast","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irwin A.","family":"Keller","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sudipta","family":"Roychowdhury","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,6,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2021-017321"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.118.022253"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.120.030227"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/STR.0000000000000074"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.120.028956"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(16)00163-X"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-023-32634-0"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2018-014678"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000092123.00938.83"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2021-017842"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2022.1063078"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1148\/82.4.602"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.31.4.379"},{"key":"e_1_3_3_15_2","first-page":"21","article-title":"Differences between MIP and MPR techniques in the carotid artery stenosis degree measurement.
