肌肉体积（MV）是了解肌肉形态和适应训练，生长和病理的重要参数。在这项研究中，我们评估了徒手三维超声（3DUS）测量内侧腓肠肌MV的有效性在成人，通常是发展（TD）儿童和脑瘫（CP）儿童。我们还评估了我们的直接测量MV和估计来自解剖横截面积（阿克萨）和肌肉长度（ML）之间的有效性，使用先前概述的方法。对各组的内侧腓肠肌进行3DUS和MRI扫描。将两种方法的图像数字化以获得MV、阿克萨和ML。测量的MV方法之间进行了比较，并与最近发表的算法得出的估计MV进行了比较。MRI和3DUS之间的MV平均差异为−0.13%（估计标准误差（SEE）= 2.23%，R2 = 0.99），两种估计方法的测量和估计MV之间的平均差异为19.82%（SEE = 4.73%，R2 = 0.99）和−3.11%（SEE = 6.55%，R2 = 0.99）。3DUS是测量成人、TD儿童和CP患者MV的有效方法。MV的估计方法在临床实践中可能是有用的，但需要在不同人群中进一步复制并仔细考虑方法。临床解剖学32：319-327，2019年。© 2018 Wiley Periodicals，Inc.
Muscle volume (MV) is an important parameter for understanding muscle morphology and adaptations to training, growth and pathology. In this study, we assessed the validity of freehand 3D ultrasound (3DUS) for measuring medial gastrocnemius MV in adults, typically developing (TD) children and children with cerebral palsy (CP). We also assessed the validity between our direct measures of MV and estimates derived from anatomical cross sectional area (ACSA) and muscle length (ML), using previously outlined methods. The medial gastrocnemius of all groups was scanned with 3DUS and MRI. Images from both methods were digitized to derive MV, ACSA and ML. Measured MV was compared between methods and compared to estimated MV derived from recently published algorithms. MV had a mean difference of −0.13% (standard error of estimate (SEE) = 2.23%, R2 = 0.99) between MRI and 3DUS and 19.82% (SEE = 4.73% and R2 = 0.99) and −3.11% (SEE = 6.55%, R2 = 0.99) mean differences between the measured and estimated MV from two methods of estimation. The 3DUS is a valid method for the measurement of MV in adults, TD children and those with CP. Estimation methods of MV may be useful in clinical practice, but require further replication on various populations and careful methodological consideration. Clin.
