超声检查因其无创、快速、安全等优点成为诊断肾动脉狭窄的首选影像学方法之一。肾动脉狭窄常用超声诊断指标多为多普勒血流参数,其需获取肾主动脉或肾内动脉多普勒频谱,对操作者的技术依赖性高,检查费时。超声造影是超声技术在肾动脉狭窄诊断中的新应用,但其中延用的多普勒血流参数指标,并未根本解决肾动脉显示困难及检查费时等问题;通过分析造影后肾实质回声的时间—强度曲线,则为无创、快速诊断肾动脉狭窄提供了新思路,有较广的研究空间。
Ultrasound has become one of the preferred imaging methods for the diagnosis of renal artery stenosis because of its advantages of non-invasive, rapid and safe. Renal artery stenosis often ultrasound diagnostic indicators for the Doppler blood flow parameters, which need access to the renal artery or renal artery Doppler spectrum, the operator of the technology-dependent, time-consuming inspection. Ultrasonography is a new application of ultrasound in the diagnosis of renal artery stenosis, but the extension of the parameters of Doppler blood flow parameters do not fundamentally solve the problems of renal artery display difficulty and time-consuming examination. By analyzing the renal parenchymal echo Time-intensity curve, it provides a new idea for non-invasive, rapid diagnosis of renal artery stenosis, there is a broader research space.
