摘　　要：目的:比较多普勒超声(Doppler ultrasonography,DUSG)、磁共振对比增强血管造影(Contrast-enhanced magnetic resonance angiography,CE-MRA)以及DUSG与CE-MRA的联合使用对肾动脉狭窄(Renal artery stenosis,RAS)的诊断价值。方法:以选择性肾动脉造影(Selective renal arteriography,SRA)为诊断RAS的金标准,将156例患者分为三组:第一组54例患者仅使用DUSG进行诊断,第二组48例患者仅使用CE-MRA进行诊断,第三组42例患者使用DUSG与CE-MRA联合诊断,观察并比较DUSG、CE-MRA这两种影像学检查方法分别使用和联合使用对RAS的诊断效能。结果:两种影像学检查方法分别使用和联合使用对RAS的诊断效能差异有统计学意义(P<0.05)。结论:DUSG是筛查RAS的首选影像学检查方法,DUSG、CE-MRA联合使用对RAS的诊断准确性最高。Objective： To compare diagnosis value of Doppler uhrasonography （ DUSG ） and contrast- enhanced magnetic resonance angiography （ CE-MRA ）, as well as combined use, in renal artery stenosis （ RAS ） . Method： Selective renal arteriography （ SRA ） was used as the gold standard for diagnosis of RAS. 156 patients were divided into 3 groups. In the first group, 54 patients were diagnosed only by DUSG. In the second group, 48 patients were diagnosed only by CE-MRA. In the third group, 42 patients were diagnosed by DUSG combined with CE-MRA. Diagnosis value between the two imaging methods were compared when they were used separately and together. Result： There were statistically significant differences in the diagnosis result of RAS when using the two imaging methods separately and together. Conclusion： DUSG is the first choice of imaging examination method for the screening of RAS, while combined use of DUSG and CE-MRA has the highest level of diagnostic accuracy.
