INTRODUCTION
Echo intensity of skeletal muscle measured by means of ultrasonography has been used to assess muscle quality, however, the heterogeneity of echo intensity has not been thoroughly investigated. Therefore, this study examined echo intensity in different sections of panoramic ultrasound images captured in the transverse plane.
METHODS
Echo intensity of the vastus lateralis was assessed in 24 men (20.2 ± 1.6 years) using panoramic ultrasonography. Echo intensity homogeneity was examined by dividing each image into 3 compartments of equal horizontal length (tertiles).
RESULTS
No differences were found between echo intensity of the anterior tertile (59.1 ± 9.1 AU), posterior tertile (56.4 ± 9.9 AU), lateral tertile (58.7 ± 9.9 AU), or the overall panoramic image (58.0 ± 8.8 AU).
CONCLUSIONS
Echo intensity of the vastus lateralis appears to be homogeneous as assessed in the transverse plane. Further research is necessary to determine if still imaging is sufficient to obtain an accurate measure of echo intensity. Muscle Nerve 56: 93-98, 2017.
引言
通过超声测量骨骼肌的回声强度已被用于评估肌肉质量，然而，回声强度的异质性尚未得到充分研究。因此，本研究检查了在横断面上采集的全景超声图像不同区域的回声强度。
方法
使用全景超声对24名男性（20.2±1.6岁）的股外侧肌回声强度进行评估。通过将每个图像水平等分为3个部分（三分位数）来检查回声强度的均匀性。
结果
在前三分位数（59.1±9.1 AU）、后三分位数（56.4±9.9 AU）、外侧三分位数（58.7±9.9 AU）或整个全景图像（58.0±8.8 AU）的回声强度之间未发现差异。
结论
在横断面上评估时，股外侧肌的回声强度似乎是均匀的。需要进一步研究以确定静态成像是否足以准确测量回声强度。《肌肉与神经》56: 93 - 98, 2017年。
