摘要
背景：应变弹性学（SE）和横波弹性学（SWE）是评估软组织弹性的新兴技术。本研究旨在确定使用SE和SWE对不同组织和解剖位置进行弹性测量的观察者之间和观察者内部的可靠性。方法：健康成年男性10例，上肢20条。测量腕部伸肌、伸总肌腱和冈上肌腱的弹性。应变比和横波速度由2名不同的检验员（检验员1有超过20年的肌肉骨骼超声经验，检验员2有1年的经验）测量两次。使用类内相关系数（ICC）评估观察者间和观察者内的信度。结果：10例患者年龄在28 ~ 35岁之间。在SE中，3个解剖位置（腕伸肌、总伸肌腱和冈上肌腱）的观察者间信度显示了相当到中等程度的一致性(ICC = 0.489, p = 0.076；ICC = 0.408, p = 0.131；ICC = 0.296, p = 0.711)。检查者1的观察者内信度仅在腕伸肌和总伸肌腱处为中等至实质性（ICC = 0.563, p = 0.039和ICC = 0.702, p = 0.006）。在SWE中，腕伸肌和冈上肌腱的观察者间信度为中等至相当（ICC = 0.756, p = 0.002和ICC = 0.565, p = 0.039）。检查者1在3个解剖位置的观察者内信度几乎是完美的(ICC = 0.843, p = 0.001；ICC = 0.800, p = 0.001；ICC = 0.825, p = 0.001)。检查者2的结果显示，腕伸肌几乎完全一致（ICC = 0.886, p = 0.001），伸总肌和冈上肌肌腱的结果中等到基本一致（ICC = 0.592, p = 0.029和ICC = 0.682, p = 0.008）。结论：SWE是一种可靠的评估软组织柔韧性的方法，但受专业知识和特定解剖部位的影响。
Reliability of Ultrasound Elastography According to Experience Level and Anatomic Location.
Backgroud: Strain elastography (SE) and shear wave elastography (SWE) are emerging techniques for evaluating the elasticity of soft tissue. This study aimed to determine interobserver and intraobserver reliability for elasticity measurements of different tissues and anatomic locations using SE and SWE.
Methods: Ten healthy adult male individuals with 20 upper extremities participated in this study. The elasticities of the wrist extensor muscle, the common extensor tendon, and supraspinatus tendon were measured. Strain ratio and shear wave velocity were measured twice by 2 different examiners (examiner 1 with over 20 years of experience in musculoskeletal sonography and examiner 2 with 1 year of experience). Interobserver and intraobserver reliability was assessed using the intraclass correlation coefficient (ICC).
Results: The 10 individuals' age ranged from 28 to 35 years. In SE, interobserver reliabilities at the 3 anatomic locations (wrist extensor muscle, common extensor tendon, and supraspinatus tendon) showed fair to moderate agreement (ICC = 0.489, p = 0.076; ICC = 0.408, p = 0.131; and ICC = 0.296, p = 0.711, respectively). The intraobserver reliabilities of examiner 1 were moderate to substantial only at the wrist extensor muscle and the common extensor tendon (ICC = 0.563, p = 0.039 and ICC = 0.702, p = 0.006, respectively). In SWE, interobserver reliabilities for the wrist extensor muscle and the supraspinatus tendon were moderate to substantial (ICC = 0.756, p = 0.002 and ICC = 0.565, p = 0.039, respectively). The intraobserver reliabilities of examiner 1 at the 3 anatomic locations were almost perfect (ICC = 0.843, p = 0.001; ICC = 0.800, p = 0.001; and ICC = 0.825, p = 0.001, respectively). The results of examiner 2 showed almost perfect agreement at the wrist extensor muscle (ICC = 0.886, p = 0.001) and moderate to substantial agreement at the tendons of the common extensor and supraspinatus (ICC = 0.592, p = 0.029 and ICC = 0.682, p = 0.008, respectively).
Conclusions: SWE is a reliable method for assessing the flexibility of soft tissue, but it is affected by expertise and the specific anatomical site.
