Dynamic values of key vessel diameter, blood velocity, and flow rate in the upper extremity were obtained in 20 healthy volunteers by means of color flow Doppler imaging with a 7.5 MHz transducer. Recordings were made of the brachial, radial, posterior radial recurrent, ulnar, and digital arteries. Radial and ulnar vessels were evaluated at both wrist and midcarpal levels. Diameter and velocity changes were followed throughout the cardiac cycle, and a true mean flow was computed. Mean diameters of the digital vessels ranged from 0.9 mm in the small finger to 1.3 mm in the thumb. Brachial flows ranged from 4.6 to 89.9 ml/min, radial flows from 0.9 to 15.3 ml/min, and ulnar flows from 0.6 to 79.9 ml/min. At the midcarpal level, flows ranged from 0.2 to 68.4 ml/min for the ulnar artery and from 0.8 to 42.9 ml/min for the radial artery. Variability between individuals was also demonstrated in artery dominance: eleven ulnar dominant, seven radial dominant, and two equal (within 25% of each other). The accuracy and ease of use of this technique in measurement of vessels are limited when vessels are less than 1.5 mm in diameter although the technique provides quantitative values to 0.5 mm.
通过使用7.5MHz换能器的彩色多普勒成像技术，在20名健康志愿者身上获取了上肢主要血管直径、血流速度和血流量的动态值。记录了肱动脉、桡动脉、桡侧返动脉、尺动脉和指动脉的情况。在手腕和腕骨中部水平对桡动脉和尺动脉进行了评估。在整个心动周期中跟踪直径和速度变化，并计算出真正的平均血流量。指动脉的平均直径范围从小指的0.9mm到拇指的1.3mm。肱动脉血流量范围为4.6至89.9ml/min，桡动脉血流量范围为0.9至15.3ml/min，尺动脉血流量范围为0.6至79.9ml/min。在腕骨中部水平，尺动脉血流量范围为0.2至68.4ml/min，桡动脉血流量范围为0.8至42.9ml/min。个体之间在动脉优势方面也存在差异：11例为尺动脉优势，7例为桡动脉优势，2例相等（彼此相差25%以内）。当血管直径小于1.5mm时，该技术在测量血管方面的准确性和易用性受到限制，尽管该技术可提供至0.5mm的定量值。
