Brief Summary

In recent years, high-frequency ultrasound, due to its higher resolution, can clearly display the superficial vascular structure and blood flow, and can detect vascular lesions early, providing a new non-invasive tool for clinical observation of the structure and blood flow of the extremity artery. The purpose of this multi-center study is to establish the normal value of high frequency ultrasound for the structure and blood flow of the extremity arteries of Chinese Han adults, and to explore the influencing factors, so as to provide a quantitative reference for the early diagnosis, degree evaluation and curative effect observation of the structure and blood flow of the extremities.

Outcome Measures

Primary Outcomes (1)

  • Intima thickness of dorsalis pedis artery and proper palmar digital artery

    Intima thickness reflects the changes of vascular wall structure and is used for early evaluation of arterial disease.

    1 day

Secondary Outcomes (1)

  • Blood flow velocity of dorsalis pedis artery and proper palmar digital artery

    1 day

Interventions

The volunteers will be given a high-frequency ultrasound examination of the extremity arteries, which is non-invasive, and the parameters of arterial structure and blood flow will be measured.
