【摘要】 目的 探讨正常兔三级肾动脉血流动力学的特点，为研究继发性肾血流动力学改变提供依据。方法 26只兔行双肾超声检查，二维图像测量肾脏大小，CDFI、CDPI定性分析肾灌注，频谱定量研究肾血流动力学指标：VS、VD 、VMN、AT、AC、PI、RI。结果 左右肾脏大小及各项血流动力学参数差异均无显著性(P>0.

    05)；三级肾动脉之间VS、VD、VMN、AC、PI、RI差异均有显著性(P<0.05)；AT在MRA与SRA之间差异无显著性(P>0.05),IRA的AT分别与MRA、SRA的AT比较，差异均有显著性(P<0.05)。结论 频谱多普勒的各项参数为研究正常兔肾血流动力学提供了有意义的信息。

    【Abstract】 Objective To explore the characteristics of hemodynamics of renal arteries in healthy rabbits in order to offer much meaningful information for further study on secondary

    hemodynamics changes of renal flow. Methods Twenty-six New Zealand white rabbits were examined. Renal size was evaluated by two-dimension ultrasound. Color Doppler flow imaging (CDFI) and color Doppler power imaging (CDPI) were used to qualitatively analyze the blood perfusion of the kidneys while spectrum was offered to study the hemodynamics characteristics of renal arteries. ......
