Abstract：Objective To evaluate the value of three dimensional dynamic contrast enhanced magnetic resonance angiography (DCE-MRA) and spiral CT angiography (SCTA) in the diagnosis of renal artery stenosis (RAS).Methods Fifty patients suspected of RAS were performed with both DCE-MRA and SCTA,and 25 patients confirmed with RAS were performed with DSA.Results DCE-MRA and SCTA in evaluation of RAS had the kappa coefficient of 0.831.In the diagnosis RAS,the sensitivity,specificity,positive and predictive value and negative predictive value of DCF-MRA (96.0％,94.0％,91.8％,98.0％) were slightly lower than those of SCTA(96.8％,95.7％,93.4％,96.7％).Conclusions DCE-MRA and CTA can accurately diagnose renal artery stenosis.ACEMRA is more safe and more appropriate for the diagnosis of the RAS compared with DCE-MRA.
