This study aims to assess correlations of blood flow volume measurements in cervical and intracranial arteries between duplex sonography and quantitative magnetic resonance angiography (qMRA).<\/jats:p><jats:p>\n          Materials and Methods\u2002Consecutive patients with suspicion of cerebral vascular pathology underwent qMRA and duplex sonography of cervical and intracranial arteries with measurement of blood flow volume in bilateral common (CCA), internal (ICA) and external carotid arteries, vertebral and basilar arteries, middle, anterior, posterior cerebral and posterior communicating arteries using 2 different ultrasound machines. Ten patients underwent all examinations twice. Correlations between blood flow volume measurements were evaluated using Spearman\u2019s correlation coefficient and inter-class correlation coefficient (ICC).<\/jats:p><jats:p>\n          Results\u2002In total, 21 subjects (15 males, mean age: 56.3\u200a\u00b1 6.2\u00a0years) were included in the study. Duplex sonography inter-investigator correlation was excellent (ICC\u200a=\u200a0.972, p\u200a&lt;\u200a0.0001) as well as intra-investigator correlations of both qMRA and duplex sonography (ICC\u200a\u02c3\u200a0.990, p\u200a&lt;\u200a0.0001). Mostly high correlations were recorded between qMRA and duplex sonography in particular cervical arteries but only low to moderate correlations were obtained for intracranial arteries. The mean differences between blood flow volume measurements were 10.9\u200a\u00b1\u200a8.1\u200a% in the CCA and its branches when using qMRA and 15.0\u200a\u00b1\u200a11.9\u200a% when using duplex
