应用SENIAM指南标准化剪切波弹性成像的探头放置：一种肌肉成像新方法
本文探讨将标准化的表面肌电传感器放置指南（SENIAM）用于超声剪切波弹性成像（SWE）时的探头定位。研究纳入31例单侧症状性膝骨关节炎患者，采集股四头肌SWE测量值，通过变异系数和图像质量图分析。结果显示所有测量肌肉的组内变异性低（平均变异系数=6.6%）且图像质量高，提示标准化探头放置对SWE可行，但需进一步研究。
要点
- SENIAM指南可用于标准化下肢肌肉SWE的探头放置。
- 股四头肌SWE测量组内变异性低，平均变异系数6.6%。
- 标准化探头放置下图像质量高，可行性好。
关键影像表现/征象
- 所有测量肌肉均显示一致的低组内变异性。
- 所有测量肌肉均显示高图像质量。
诊断标准与关键数值
- 平均变异系数=6.6%。
临床应用与阅片要点
- 可参考SENIAM指南标准化下肢肌肉SWE的探头放置以减少方法学变异。
局限性
- 需在不同肌肉群、临床人群和研究应用中进一步研究。

INTRODUCTION: Ultrasound shear wave elastography (SWE) is used to assess musculoskeletal tissue properties, but methodological inconsistencies, particularly in probe placement, have limited the generalizability of findings. Therefore, this technical note investigated the use of standardized surface muscle electromyography sensor placement guidelines for ultrasound transducer placement during SWE on lower-limb muscle tissue.
METHODS: A total of 31 individuals with unilateral symptoms of knee osteoarthritis were recruited from the community. Quadriceps muscle SWE measures were acquired and analyzed across sites with coefficients of variance and image quality maps.
RESULTS: All measured muscles demonstrated consistently low intra-trial variability (mean coefficient of variance = 6.6%) and high image quality.
CONCLUSION: The findings suggest that standardization of transducer placement is feasible for SWE, but further investigations across varying muscle groups, clinical populations and research applications are required.
