Measurement variability of carotid atherosclerosis: real-time (B-mode) ultrasonography and angiography.
To quantify the within- and between-reader agreement of carotid B-mode ultrasonography and angiography interpretation, images from 117 patients examined by both modalities were read multiple times. Angiographic measurements were more reproducible than those of B-mode scans for all parameters except lesion width, but variations for B-mode scan measurements were similar to those for angiographic ...
متن کاملCorrelation of carotid bruits and carotid atherosclerosis detected by B-mode real-time ultrasonography.
The extent of carotid atherosclerosis evaluated by B-mode real-time ultrasound and the presence of bruits established by carotid phonoangiography were determined in 1,107 patients. Unilateral bruit was associated with increased atherosclerosis compared with no bruit (p less than or equal to 0.0001). However, there was no association between laterality of the bruit and the degree of atherosclero...
متن کاملCarotid atherosclerosis: high-resolution real-time sonography correlated with angiography.
The merits of high-resolution real-time sonography in detection of plaque and estimation of stenoses were compared with angiography in 97 carotid bifurcations from 50 consecutive patients. For flow-reducing lesions, that is, stenosis greater than or equal to 50% or complete occlusion, sonographic accuracy was 86% and the mean difference in percentage narrowing was 17% (SD, 21.6%). For detection...
متن کاملMeasurement of carotid artery stenosis: correlation analysis between B-mode ultrasonography and contrast arteriography
PURPOSE To evaluate the efficacy of B-mode ultrasonography (US) in measurement of carotid stenosis% (CS%). METHODS One hundred and thirth-three carotid arteries in 96 patients who underwent both carotid US and carotid arteriography (CA) were included in this retrospective study. To measure CS% on US, a cross sectional view of the most stenotic segment of the internal carotid artery was captur...
متن کاملNoninvasive measurement of early atherosclerosis by high-resolution B-mode ultrasonography.
Development of sophisticated noninvasive methods permits the identification of asymptomatic subjects with early atherosclerosis. High-resolution B-mode ultrasound measurement of the intima-media thickness (IMT) is a safe and reproducible way of quantifying early changes in the arterial wall, mainly in the carotid arteries. Increased carotid IMT is associated with major cardiovascular risk facto...
