Abstract:
Objective To evaluate the value of linear array ultrasonic with high-frequency in the diagnosis of renal artery stenosis (RAS).Methods 1 828 patients who were doubted with RAS were studied.All of them were checked by ultrasonic with convex array probe and linear array probe.Results The sensitivity,specificity,false positive rate,false negative rate of convex array probe were 8.20％,97.10％,2.90％,21.80％.The sensitivity,specificity,false positive rate,false negative rate of linear array probe were 91.13％,99.80％,0.20％,8.87％.Conclusion Linear array with high-frequency can keep the measurement angle less than 60°,and can show the plaque,nature of the plaque and narrow rate of renal artery.It may be more helpful in the diagnosis of RAS.
