| 目的 探讨应用实时剪切波成像测量胸锁乳突肌杨氏模量值时声束平面与肌束不同角度对测量值的影响。方法 选取210名健康志愿者，按年龄分为青年组（20~39岁）、中年组（40~59岁）和老年组（≥60）3组；同时按性别分为男性组和女性组。采用Supersonic Imagine AixPlorer型Shear WaveTM实时剪切波弹性成像超声诊断仪，测量声束平面与肌束成不同角度（0°、30°、60°、90°）时的杨氏模量值；对不同组别杨氏模量值进行统计学分析。结果 0°、30°、60°、90°时的杨氏模量值分别为（27.54±1.46）kPa、（14.87±3.05）kPa、（11.27±2.12）kPa、（9.33±1.94）kPa，两两比较差异均有统计学意义（P均<0.05）；不同性别和年龄组间杨氏模量值差异均无统计学意义。结论 胸锁乳突肌杨氏模量值受声束平面与肌束角度的影响，但不受性别和年龄的影响。 |

| Objective To investigate the impact of the angle of beam plane and muscle bundle on the Young's modulus value of sternocleidomastoid measured with real time shear wave imaging. Methods Totally 210 healthy volunteers were enrolled and classified as young-aged group (20 to 39 years old), middle-aged group (40 to 59 years old) and elderly group (more than or equal to 60 years old), as well as male group and female group. The Young's modulus were measured at different angles (0°, 30°, 60°and 90°) of beam plane and muscle bundle by AixPlorer type Shear WaveTM real-time shear wave elastography ultrasound diagnostic apparatus. Result The Young's modulus value of 0°, 30°, 60°and 90°group were (27.54±1.46)kPa, (14.87±3.05)kPa, (11.27±2.12)kPa and (9.33±1.94)kPa, and statistically significant differences were found between each two angles (all P<0.05). There was no statistical difference of Young's modulus value among different aged groups, nor between gender groups. Conclusion Young's modulus value of sternocleidomastoid can be impacted by the angle of beam plane and muscle bundle, but not by gender or age. |
