INTRODUCTION
In this study we examined the test-retest reliability of panoramic brightness-mode ultrasound (US) imaging to simultaneously measure both muscle size and quality from a single US image.
METHODS
Sixteen healthy, recreationally active men (age = 20.9 ± 2.5 years) volunteered for this investigation. Test-retest reliability was evaluated using intraclass correlation coefficients (ICCs) and the standard error of measurement as a percentage of the mean (SEM%). Muscle size [cross-sectional area (CSA)], and muscle quality [echo intensity (EI)] of the medial gastrocnemius were examined on 2 separate days.
RESULTS
These measures demonstrated acceptable reliability between assessment days with ICCs and SEM% of 0.914 and 0.720 and 5.830 and 3.680 for CSA and EI, respectively.
CONCLUSIONS
These results suggest that panoramic US imaging may be a reliable technique for simultaneous assessment of both muscle size and quality from a single US scan.
简介
本研究旨在检验全景亮度模式超声（US）成像技术在单次 US 图像中同时测量肌肉大小和质量的重测信度。
方法
本研究共纳入 16 名健康、有规律运动的男性志愿者（年龄=20.9±2.5 岁）。采用组内相关系数（ICC）和测量误差百分比（SEM%）作为重测信度的评估指标。分别在 2 天内对内侧比目鱼肌的肌肉大小（横截面积，CSA）和肌肉质量（回声强度，EI）进行检测。
结果
CSA 和 EI 的 ICC 值分别为 0.914 和 0.720，SEM%分别为 5.830%和 3.680%，提示这些指标在评估日之间具有良好的重测信度。
结论
全景 US 成像技术可能是一种可靠的技术，可通过单次 US 扫描同时评估肌肉大小和质量。
