B-Flow Evaluation of Carotid Arterial Stenosis: Initial Experience¹

¹ From the University Clinic for Radiology, Department of Angiography and Interventional Radiology (R.A.B., J.L.), and the University Clinic for Internal Medicine II, Department of Angiology (M.R., I.K., R.A., E.M.), Vienna General Hospital, Währinger Gürtel 18-20, A-1090 Vienna, Austria. Received August 16, 2001; revision requested September 13; final revision received March 20, 2002; accepted March 26. Address correspondence to R.A.B. (e-mail: robert.bucek@akh-wien.ac.at).

In this prospective pilot trial, B-flow ultrasonographic (US) imaging was compared with color duplex flow US in the evaluation of internal carotid arterial stenosis. Despite almost excellent interobserver variability, none of the investigated B-flow imaging parameters correlated with those of duplex US. In conclusion, the investigated B-flow imaging parameters cannot be used in evaluating internal carotid arterial stenosis.
