| 摘要目的本研究探讨正常人腕部正中神经不同位置的剪切波测值差异。方法剪切波弹性成像检查56例健康志愿者的112条腕管处的正中神经，比较近、远端腕骨处正中神经剪切波速度的差异，并分析与年龄、性别和BMI等相关性。结果受试者正中神经近端腕骨水平剪切波速度是（3.80±0.45）m/s，95%置信区间是（3.67，3.93）m/s；远端腕骨水平剪切波速度是（4.63±0.47）m/s，95%置信区间为（4.49，4.76）m/s。正中神经剪切波速度与年龄呈正相关，不同性别、同一水平的正中神经剪切波速度测值差异有统计学意义。结论正中神经在腕部不同区域的剪切波速度是不同的，性别、年龄均是影响剪切波速度测值的重要因素，这些可为进一步的临床研究提供参考。 |

| AbstractObjective The aim of this study was to investigate the different shear wave elastography (SWE) in different wrist positions ofthemedian nerve from healthy individuals.Methods The study included 56 healthy volunteers (112 wrists). The difference of shear wave velocity was compared between the proximal and distal carpal bones and the correlation was analyzed with age, sex, and BMI. Results The shear wave velocity at the proximal carpal bone level of the middle nerve was 3.80±0.45 m/s,95% the confidence interval was (3.67,3.93) m/s; The shear wave velocity at the distal carpal bone level was 4.63±0.47,95% the confidence interval was (4.49,4.76) m/s. The shear wave velocity of the median nerve was positively correlated with age. The shear wave velocity in the same position of the median nerve was statistically significant different in different sex. Conclusion The shear wave velocity ofthemedian nerve in different regions of the wrist is different. Sex and age are both important factors affecting the shear wave velocity, and these can provide reference for further clinical studies. |
