摘　　要：目的比较彩色多普勒超声(CDUS)和对比增强磁共振血管造影(CE-MRA)在评价肾动脉狭窄(RAS)中的应用价值。资料与方法回顾性分析50例RAS患者共100条肾动脉的CDUS及CE-MRA资料。所有患者最终均经数字减影血管造影(DSA)检查确认诊断。比较CDUS与CE-MRA对RAS检出率的差异。采用受试者工作特征(ROC)曲线评价CDUS与CE-MRA对RAS的诊断效能。结果CDUS与CE-MRA对RAS的检出率差异无统计学意义(57%比60.0%,P>0.05)。CDUS诊断RAS的ROC曲线下面积为0.88(95% CI 0.810.90),CE-MRA诊断RAS的ROC曲线下面积为0.79(95% CI 0.710.86),差异有统计学意义(Z=2.345,P<0.05)。结论CDUS及CE-MRA均具有较高的RAS检出率,其中CDUS具有更高的诊断效能。Purpose To evaluate the diagnostic value of color Doppler ultrasound(CDUS)and contrast-enhanced magnetic resonance angiography(CE-MRA)in patient with renal artery stenosis(RAS).Materials and Methods Fifty patients with 100 renal arteries confirmed as RAS by digital subtraction angiography(DSA)were retrospectively enrolled,CDUS and CE-MRA data of these patients with RAS were analyzed,respectively.The diagnostic differences in patients with RAS were compared between CDUS and CE-MRA,and the diagnostic efficiency on RAS between CDUS and CE-MRA was evaluated via receiver operating characteristic curve(ROC).Results There was no significant difference in diagnosis of RAS between CDUS and CE-MRA.(57% vs.60.0%,P>0.05).The area under curve(AUC)of CDUS was 0.88(95 %CI 0.81-0.90),while AUC of CE-MRA was 0.79(95% CI 0.71-0.86)in patients with RAS.Conclusion Both CDUS and CE-MRA could be available for the diagnosis of RAS,with higher diagnostic efficiency in CDUS.
