摘要 目的探讨SonoVue声学造影在肾动脉检测中的可行性和价值。方法35例有高血压病史患者先观察肾动脉二维及彩色多普勒血流显像,然后进行SonoVue声学造影,对照分析造影前、后检查结果。结果肾动脉显像分0-3级。造影前肾动脉肾外段基础显像2级8例,1级20例,0级7例;造影后肾动脉显像3级16例,2级19例,造影前后有显著差异(P〈0.01),其中32例显示肾动脉正常(1例左侧见副肾动脉),3例显示右肾动脉起始段狭窄。静脉注入SonoVue造影剂后全部患者均观察到肾动脉彩色血流信号增强,显像增强效应持续。结论SonoVue声学造影能显著改善彩色血流显像,提高肾动脉显像分级;造影剂能显示肾动脉管道及管壁变化,直接测量管腔的狭窄程度,可作为肾动脉狭窄的初筛诊断,对某些彩色多普勒假阳性假阴性病例起到鉴别作用。
