目的：通过检测正常人双侧颈总动脉、桡动脉瞬时波强（Wave intensity，WI）及桡动脉寸口脉象各参数，分析颈总动脉、桡动脉WI参数与寸口脉象各参数间的相关性，并将两处WI参数比较分析，探讨将WI技术运用于人迎脉、寸口脉脉象研究的可行性及两处WI各参数的意义，丰富脉象研究的信息量，为脉象研究探索新途径。方法：应用ALOKA公司Prosound α7彩色多普勒超声诊断仪和DDMX-100脉象仪对40例正常人双侧颈总动脉及桡动脉的WI和桡动脉脉象相关指标进行检测并进行相关性分析。对双侧颈总动脉及桡动脉处的WI检测结果进行比较分析。结果：颈总动脉处及桡动脉处的WI检测各参数均与寸口脉脉象仪检测各参数具有良好的相关性。颈总动脉WI各参数与桡动脉WI各参数差异有显著统计学意义。结论：颈总动脉与桡动脉处的WI技术参数与桡动脉脉象仪各参数具有良好的相关性，因此WI技术可应用于人迎及寸口脉象研究，具有可行性，能为中医脉象的研究拓展新途径。颈总动脉与桡动脉的解剖结构及生理学基础不同，因此人迎脉与寸口脉反映的机体信息不同，WI技术拓展了脉象研究的检测部位，对人迎脉与寸口脉的研究均可以提供更丰富的信息。

Objective: To analyze the feasibility of applying wave intensity(WI) technology in the study of Renying and Cunkou pulse manifestation through applying WI technology to detect bilateral radial arteries and common carotid arteries. Methods: Forty cases of healthy people were enrolled. Prosound α7 color Doppler ultrasonography of ALOCK company was used to detect the WI technology parameters of the bilateral radial arteries and bilateral common carotid arteries. DDMX-100 pulse condition apparatus was applied to detect Cunkou pulse manifestation parameters. The correlation of the parameters was analyzed. The WI parameters of bilateral radial arteries and bilateral common carotid arteries were compared and analyzed. Results: There were good correlations between the WI technology parameters of bilateral radial arteries as well as common carotid arteries and Cunkou pulse manifestation parameters. The difference between the WI technology parameters of the common carotid artery and those of the radial artery was statistically significant. Conclusion: This study demonstrated that the good correlation exists between the WI technical parameters of radial artery, common carotid artery and the pulse instrument parameters of radial artery. Therefore, WI technology can be applied to the study of Renying and Cunkou pulse condition.
