肌肉回声强度已被证明与肌肉疾病的疾病状态相关，包括杜氏肌营养不良症（DMD）。我们报告的影响sonographer施加负荷测量肌肉echo intensity.MethodsQuadriceps超声扫描进行了22名健康男孩和16名男孩DMD之间的年龄为2.2和15.3岁。传感器接触力线性增加，从1.5到10 N，回声强度测量through.ResultsEcho强度与应变线性增加，在42（95%置信区间[CI]：21-63）和74（95%CI：49-98）在健康和DMD人群，分别。回声强度可靠性在低应变下为中等（组内相关系数[ICC] = 0.82），在高应变下得到改善（ICC = 0.92）。讨论超声医师施加的负载在回声强度测量中引入了误差，但可以通过在接近最大压缩水平下测量回声强度来最小化。肌肉神经57：423-429，2018
IntroductionMuscle echo intensity has been shown to correlate with disease status in muscle disorders, including Duchenne muscular dystrophy (DMD). We report the effect of sonographer‐applied load on measurements of muscle echo intensity.MethodsQuadriceps ultrasound scans were performed on 22 healthy boys and 16 boys with DMD between the ages of 2.2 and 15.3 years. Transducer contact force was increased linearly from 1.5 to 10 N, and echo intensity was measured throughout.ResultsEcho intensity increased linearly with strain at a rate of 42 (95% confidence interval [CI]: 21–63) and 74 (95% CI: 49–98) in the healthy and DMD populations, respectively. Echo intensity reliability was moderate at low strain (intraclass correlation coefficient [ICC] = 0.82) and was improved at high strain (ICC = 0.92).DiscussionSonographer‐applied load introduces error in measurements of echo intensity, but it can be minimized by measuring echo intensity at near‐maximal levels of compression.Muscle Nerve57: 423–429, 2018
