BACKGROUND.: The aim of this study was to assess the accuracy and efficacy of B-flow imaging (BFI) in the diagnosis and measurement of renal artery stenosis (RAS) compared with color duplex ultrasonography (CDU) and digital subtraction angiography (DSA). METHODS.: Fifty-one consecutive patients with RAS diagnosed and measured with DSA were subsequently and independently examined with BFI for the measurement of residual lumen diameter, and with CDU for the measurement of peak systolic velocity and renal-aortic velocity ratio. The diagnostic performances of BFI and CDU in determining 60-99% RAS were compared by receiver operating characteristic curve analysis. The agreement between DSA and BFI stenosis measurements was evaluated with Bland-Altman method. RESULTS.: The area under curve was 0.983 for BFI and 0.959 for CDU, without a significant difference in diagnostic performances (p = 0.26). BFI yielded an 88% sensitivity and 94% specificity in the diagnosis of RAS with a 3% underestimation of RAS compared to DSA (95% confidence interval 1.4%, 4.6%). CONCLUSIONS.: BFI is an accurate method that minimally underestimates RAS. It might provide an additional benefit to CDU in patients with RAS. © 2011 Wiley Periodicals, Inc. J Clin Ultrasound 2011; |
