Nerve cross-sectional area reference values have been reported for many nerves, but there have been few studies in pediatric and geriatric populations. This study was conducted to determine the influence of age on nerve cross-sectional area.
Thirty-two children (3 months to 16 years) and 20 geriatric adults (67-92 years) without known neurologic conditions underwent bilateral ultrasound to measure the area of the following nerves: median at the wrist and forearm; ulnar at the wrist and elbow; radial in the spiral groove; sciatic in the distal thigh; fibular at the knee; tibial at the knee and ankle; and sural at the ankle.
In general, nerve cross-sectional area increased with age. Nerve size correlated most closely with age, but a correlation was also seen with body mass index.
Nerve cross-sectional area increases with age, which is important to note when using ultrasound to evaluate children and geriatric patients.
已经有许多神经的横截面积参考值被报道，但在儿科和老年人群中研究较少。本研究旨在确定年龄对神经横截面积的影响。
32 名儿童（3 个月至 16 岁）和 20 名老年成年人（67-92 岁），均无已知的神经疾病，接受双侧超声检查以测量以下神经的横截面积：腕关节和前臂的正中神经；腕关节和肘关节的尺神经；螺旋沟的桡神经；大腿远端的坐骨神经；膝关节的腓总神经；膝关节和踝关节的胫神经；以及踝关节的腓肠神经。
总的来说，神经横截面积随年龄增长而增加。神经大小与年龄的相关性最强，但与体重指数也有相关性。
神经横截面积随年龄增长而增加，这在使用超声评估儿童和老年患者时很重要。
