Magnet ic resonance angiography ruled out extra\u2010 and intracranial large vessel disease in 36% of the patients. MRA also demonstrated extra\u2010 or intracranial disease in 56% (probably symptomatic in 31, possibly symptomatic in 18, and asymptomatic in 17 patients), and provided no information in 8% of the 118 patients. Among the 176 major vessels visualized by both MRA and conventional angiography, conventional angiography confirmed the presence of 9\/10 extracranial and 32\/40 intracranial large vessel abnormalit ies detected on MRA. There were two false\u2010negative findings on MRA: occlusion of a distal branch of middle cerebral artery, and an asymptomatic posterior cerebral artery stenosis. Magnetic resonance angiography is a clinically useful method for screening extra\u2010 and intracranial disease in patients with brain infarction and selecting high\u2010yield patients for conventional angiography.<\/jats:p>","DOI":"10.1111\/jon19988265","type":"journal-article","created":{"date-parts":[[2016,2,8]],"date-time":"2016-02-08T10:18:48Z","timestamp":1454926728000},"page":"65-70","source":"Crossref","is-referenced-by-count":18,"title":["Magnetic
