背景：可以测量肌肉结构的B型超声图像与可以评估肌肉硬度的超声应变弹性图并排显示。目的：探讨超声应变弹性成像技术同时测量肌肉结构和肌肉硬度的方法。材料和方法：利用超声应变弹性成像技术同时测量腓肠肌内侧的肌肉结构参数(肌肉厚度、羽状角和肌束长度)和肌肉硬度。肌肉结构参数的单独测量也被执行，以用作同时测量的参考值。在背屈20度、中立位和足底屈曲30度时进行两次测量。结果：同时测量得到的肌肉构筑参数的变异系数(=0.97)。然而，同时测量和单独测量之间的任何肌肉结构参数都没有显著差异(均P>；0.05)。结论：使用超声应变弹性图同时测量肌肉结构和肌肉硬度是可行的。
Background: The B-mode ultrasound image that can measure muscle architecture is displayed side by side with the ultrasound strain elastogram that can assess muscle hardness. Consequently, muscle architecture can be measured concurrently with muscle hardness using ultrasound strain elastography.Purpose: To demonstrate the measurement of muscle architecture concurrently with muscle hardness using ultrasound strain elastography.Material and Methods: Concurrent measurements of muscle architectural parameters (muscle thickness, pennation angle, and fascicle length) and muscle hardness of the medial gastrocnemius were performed with ultrasound strain elastography. Separate measurements of the muscle architectural parameters were also performed for use as reference values for the concurrent measurements. Both types of measurements were performed twice at 20 degrees dorsiflexion, neutral position, and 30 degrees plantar flexion.Results: Coefficients of variance of the muscle architectural parameters obtained from the concurrent measurements (= 0.97). However, there were no significant differences in any muscle architectural parameters between the concurrent and separate measurements (all P > 0.05).Conclusion: The use of ultrasound strain elastography for the concurrent measurement of muscle architecture and muscle hardness is feasible.
