Method From July 2011 to July 2013, we selected patients with suspected hyperacute stroke (&lt; 6 hours). Intracranial and cervical arteries were scrutinized on CTA and their imaging features were correlated with concurrent subtype of stroke. Results Stroke was documented in 50\/106 selected patients (47.2%) based on both clinical grounds and imaging follow-up (stroke group), with statistically significant arterial stenosis and vulnerable plaques on CTA. Intracranial large artery disease was demonstrated in 34% of patients in the stroke group. Partial territorial infarct prevailed (86%) while artery-to-artery embolization was the most common stroke mechanism (52%). Conclusion Multidetector CTA was useful for the etiologic work-up of hyperacute ischemic stroke and facilitated the knowledge about the topographic pattern of brain infarct in accordance with its causative mechanism.<\/jats:p>","DOI":"10.1590\/0004-282x20150034","type":"journal-article","created":{"date-parts":[[2015,5,20]],"date-time":"2015-05-20T19:31:21Z","timestamp":1432150281000},"page":"408-414","source":"Crossref","is-referenced-by-count":3,"title":["Multidetector
