| 摘 要： | 目的研究松弛和紧张状态下肱二头肌肌腹的杨氏模量值差异。方法 141例男性健康志愿者,年龄16～34岁,中位年龄22岁。使用法国Supersonic公司的AixPlore型实时定量剪切波弹性成像超声诊断仪,L4-15线阵探头沿肱二头肌肌腹肌束方向检查,启动超声仪器弹性成像模式(SWE)模式,然后使用其定量分析系统Q-BOX分别测量二头肌处于松弛与紧张状态下的杨氏模量值。结果紧张状态下肱二头肌肌腹杨氏模量值为(123.658±31.392)kPa,松弛状态下杨氏模量值为(45.658±13.479)kPa,两者比较差异具有统计学意义(P=0.0000)。结论剪切波弹性成像技术可检测肱二头肌肌腹在松弛和紧张状态下杨氏模量值差异,紧张状态下较松弛状态下模量值大;定量超声弹性成像技术用于肌肉组织疾病检查,使提供常规超声之外的诊断信息成为可能。

| Abstract: | Objective To explore the difference of Young＇ s modulus in the biceps brachii during muscle relaxation and tension. Methods A total of 141 healthy male volunteers with age range from 16 to 34 years （ mean 22 years old ） were included in the study. A shear-wave elasto-sonography （ AixPlorer model, Supersonic Imagine, Aix en Provence, France） coupled with a linear array transducer array （4-15 MHz） was used. The scanner was set at the SWE mode and then at Q-BOX mode and the ultrasound trans- ducer was placed directly above the biceps brachii belly and carefully aligned with the muscle bundle. The elastic moduli of the biceps brachii were measured during muscle relaxation and tension in all 141 volun- teers. Results The Young＇ s modulus of biceps brachii was 123. 658 ±31. 392 kPa during muscle tension and 45. 658 ± 13. 479 kPa during muscle relaxation, respectively with statistical significance （P = 0.0000）, Conclusion The Young＇ s modulus of the biceps brachii was higher during muscle tension than those during muscle relaxation. |
