健康犬肾动脉阻力指数的测量

本试验对健康犬进行了彩色多普勒超声探查，建立了健康犬多普勒超声参数的参考值。首先对19只健康犬进行普通B型超声，彩色多普勒血流成像(color doppler flow imaging,CDFI)，脉冲多普勒频谱检查，对探查的数据进行统计分析，得出健康犬正常多普勒超声参数的参考值（以平均值±标准差表示）。对健康犬进行多普勒超声探查统计后发现，肾动脉阻力指数有较好的重复性，左、右肾脏之间的相似度较高，可以作为健康犬正常超声参数的指标。

Measurement of Resistance Index of Renal Arteries in Healthy Dogs

The purpose of this research was to examine healthy dogs by using color doppler ultrasonography, establish healthy dogs’ doppler ultrasound indices. Nineteen healthy dogs were tested by B-mode ultrasonic, CDFI and PW. The results were analyzed to establish the doppler ultrasound index of healthy dogs (showed as mean ± standard deviation). This study found resistance index of renal arteries was positively repeatable. The data collected form left and right kidneys were similar, which could be considered as normal ultrasound index.
