The use of renal artery Doppler ultrasound for the diagnosis of renal artery stenosis is a well-established technique in selected populations, but the technical failure rate of the examination leading to incomplete studies is a major drawback. The results of ultrasound contrast-enhanced renal artery Doppler for renal artery stenosis, using the echo-enhancing agent, Levovist, are reported here. Sixteen patients (22 arteries) were examined with Levovist. The technical success rate of these examinations was 91%, and all four renal artery stenoses were correctly identified. It is concluded that the use of ultrasound contrast (Levovist) increases the technical success rate of renal artery Doppler ultrasound in this setting, with similar accuracy to unenhanced Doppler examinations.
在特定人群中，使用肾动脉多普勒超声诊断肾动脉狭窄是一项成熟的技术，但检查的技术失败率导致研究不完整是一个主要缺点。本文报告了使用回声增强剂声诺维进行超声造影增强肾动脉多普勒检查肾动脉狭窄的结果。16例患者（22条动脉）接受了声诺维检查。这些检查的技术成功率为91%，所有4例肾动脉狭窄均被正确识别。结论是，在这种情况下，使用超声造影剂（声诺维）可提高肾动脉多普勒超声的技术成功率，其准确性与未增强的多普勒检查相似。
