Our aim was to evaluate the feasibility of using shear wave elastography (SWE) to assess first extensor compartment tendons rigidity and its alterations with tenosynovitis.
We performed B-mode ultrasound and SWE to total number of 80 participants. All participants were evaluated clinically to call the diagnosis of de Quervain tenosynovitis or to rule out the diagnosis. We composed 2 groups. Group 1 included 40 healthy volunteers (33 females and 7 male participants with ages ranging from 24 to 60 years, median age was 37.5 years) and group 2 had 40 de Quervain patients (32 females and 8 male patients with ages ranging from 25 to 51 years, median age was 34 years). SWE measurements were repeated 3 times and arithmetic average was used for the final SWE value.
The median SWE value of healthy group (group 1) was 72kPa and the de Quervain patient group (group 2) was 29kPa. Two groups demonstrated statistically significant difference (p<0.001). The ROC curve analysis was performed and the SWE value of 40.5kPA was calculated as a cut-off value for the diagnosis of de Quervain tenosynovitis with 95% specificity and 85% sensitivity.
SWE modality can provide useful data regarding de Quervain tenosynovitis.
本研究旨在评估应用剪切波弹性成像（SWE）评估第一伸肌间隔肌腱刚性及其与腱鞘炎改变的可行性。
我们对总共 80 名参与者进行了 B 型超声和 SWE 检查。所有参与者均进行了临床评估，以确诊或排除狭窄性腱鞘炎。我们将参与者分为两组。组 1 包括 40 名健康志愿者（33 名女性和 7 名男性，年龄 24 至 60 岁，中位年龄 37.5 岁），组 2 包括 40 名狭窄性腱鞘炎患者（32 名女性和 8 名男性，年龄 25 至 51 岁，中位年龄 34 岁）。对 SWE 测量值重复测量 3 次，取平均值作为最终的 SWE 值。
健康组（组 1）的中位 SWE 值为 72kPa，狭窄性腱鞘炎患者组（组 2）的中位 SWE 值为 29kPa。两组之间存在显著差异（p<0.001）。进行 ROC 曲线分析，得出 SWE 值为 40.5kPa 时可作为狭窄性腱鞘炎诊断的截断值，具有 95%的特异性和 85%的敏感性。
SWE 模式可为狭窄性腱鞘炎的诊断提供有用的数据。
