Abstract: Objective To compare contrast-enhanced ultrasound and conventional ultrasound in determining artery stenosis of varying degrees of accuracy. Methods Using conventional ultrasound and contrast-enhanced ultrasound renal artery stenosis was diagnosed.And the renal artery diameter stenosis were measured the extent to which digital subtraction angiography (DSA) as the standard diagnostic accuracy of two methods to determine the rate. Results 50 patients were diagnosed as renal artery stenosis with DSA,21 patients stenosis rate 30%-49%,23 patients stenosis rate 50%-75%,6 patients stenosis rate ＞75%.diagnose accordance rate 78%(38/50)with conventional color doppler and 92% (46/50) with contrast-enchanced ultrasound.The difference was statistically significant (P＜0.05＝. ConclusionUsing ultrasound imaging of the renal artery stenosis to determine the degree had higher accuracy than the conventional ultrasonic testing method,was suitable for clinical application.
