摘　　要：目的探讨非对比剂增强MRA在诊断肾动脉狭窄的应用价值。方法选取46例疑诊肾动脉狭窄患者,行多普勒超声(DUS)、多排螺旋CTA(MSCTA)及非对比剂增强MRA检查,评价三种影像学检查方法的优、缺点。结果 DUS诊断肾动脉狭窄的敏感性及准确性明显低于MSCTA及非对比剂增强MRA,后两者诊断的一致性很高。结论 DUS、MSCTA及非对比剂增强MRA均能诊断肾动脉狭窄,非对比剂增强MRA敏感性及准确性很高,且更安全,可作为首选的筛查方法。Objective To investigate the value of non contrast enhanced MRA in the diagnosis of renal artery stenosis.Methods A total of 46 patients with suspected renal artery stenosis,Doppler ultrasound(DUS),multi slice spiral CTA(MSCTA)and non contrast enhanced MRA examination,the advantages and disadvantages of three kinds of imaging methods of evaluation.Results The sensitivity and accuracy of DUS in diagnosing renal artery stenosis were significantly lower than that of MSCTA and non contrast enhanced MRA,and the latter diagnosis was highly consistent.Conclusion DUS,MSCTA and non contrast enhanced MRA can diagnose renal artery stenosis.Non contrast agents enhance MRA sensitivity and accuracy,it is safer and can be used as the preferred screening method.
