摘要:

文题释义:

实时剪切波弹性成像:是采用探头发射安全的声辐射脉冲控制技术,在组织不同深度上连续聚焦,产生Mach Cone效应,被聚焦部位组织粒子高效地振动产生剪切波,由于剪切波是横波,在生物体内传播速度为1-10 m/s,故可利用达20 000帧/s的超快速成像系统捕获、追踪剪切波得到实时的弹性成像图。
正中神经:由分别发自臂丛内侧束和外侧束的内侧根和外侧根汇合而成。正中神经在臂部沿肱二头肌内走行,降至肘窝后,向下穿旋前圆肌和指浅屈肌腱弓后在前臂正中下行,于指浅、深屈肌腱之间到达腕部,后行于桡侧腕屈肌腱与掌长肌腱之间,并进入屈肌支持带深面的腕管,最后在掌腱膜深面分布至手掌。在腕管内,正中神经易因周围结构的炎症、肿胀和关节内病变而受压损伤,出现腕管综合征。

背景:实时剪切波弹性成像技术可无创测量组织弹性,目前较多地应用于甲状腺、乳腺等软组织疾病,而应用于周围神经及其病变的研究相对少见。
目的:使用实时剪切波弹性成像技术量化评估健康人正中神经的重测信度及测试者间信度,探究同一测量位点正中神经长轴与短轴弹性模量的相关性。
方法:随机招募20名健康受试者参与该试验,10名男性,10名女性。在信度试验中,测试者A和B分别使用实时剪切波弹性成像技术测量受试者利手侧、非利手侧正中神经长轴放松状态时的弹性模量;5 d后,测试者A以相同的测量方法对受试者正中神经弹性进行量化评估。此外,使用实时剪切波弹性成像技术在受试者腕横纹处测量正中神经长轴以及短轴的弹性模量完成相关试验。
结果与结论:①在信度试验中,利手侧正中神经的测试者间信度表现为优秀:其组内相关系数为0.98,重测信度优秀(组内相关系数=

0.96);非利手侧,测试者间信度和重测信度均表现为好(组内相关系数=0.78,0.86);②正中神经长轴与其短轴弹性模量之间无相关性(r=0.039,P=0.87);③提示剪切波弹性成像技术能准确量化评估出健康人利手侧以及非利手侧正中神经弹性模量特征,且可信度较高;此外通过相关性试验可推测:相较于临床上使用正中神经长轴弹性特征作为常规参考指标,其短轴弹性模量的变化数据可信度不高。

Abstract: BACKGROUND: Real-time shear-wave elastography can display tissue elasticity noninvasively, At present, it is mostly used in the study of soft tissue diseases such as thyroid gland and mammary gland, but rarely used in the study of peripheral nerves and their lesions.
OBJECTIVE: To calculate the test-retest and inter-operator reliability of assessing median nerve elasticity by real-time shear-wave elastography and to explore the relationship between the elastic modulus of macroaxis and minor axis of the median nerve at the same measurement site.
METHODS: A total of 20 healthy subjects, including 10 men and 10 women, were randomly recruited in this study. In the reliability test, two operators A and B assessed elastic modulus of the long axis of the median nerve on the handed and unhanded sides using the real-time shear-wave elastography, respectively. Five days later, operator A quantified the median nerve elasticity repeatedly using the same measurement method. In addition, real-time shear-wave elastography was used to measure the elastic modulus of the macroaxis and minor axis of the median nerve at the rasceta. 
RESULTS AND CONCLUSION: In the reliability test, the inter-operator and test-retest reliabilities of the median nerve elastic modulus on the handed side were excellent with the intraclass correlation coefficient of 0.98 and 0.96, respectively. The intra-operator and test-retest reliabilities on the unhanded side were also excellent with the intraclass correlation coefficient of 0.78 and 0.86, respectively. There was no correlation between the elastic modulus of the macroaxis and minor axis of the median nerve (r=0.039, P=0.87). These findings indicate that real-time shear-wave elastography can quantitatively evaluate the elastic characteristics of the median nerve in healthy subjects on the handed or unhanded side with a high reliability. In addition, it can be inferred that the elastic modulus of the minor axis of the median nerve is not reliable in the correlation test, relative to that of the macroaxis of the median nerve that can act as a routine reference index in clinical practice.

Key words: shear-wave elastography, median nerve, elastic modulus, reliability, correlation
