【摘要】：目的研究声脉冲辐射力成像检查正常跟腱的可行性并评估正常跟腱的弹性特征。方法 39例健康志愿者的双侧跟腱接受灰阶超声、能量多普勒超声和ARFI成像检查。检查时将跟腱分为近段(肌-腱结合部)、中段(跟腱跟骨附着端以上2~6cm处)和远段(跟腱跟骨附着端)3部分,每个部位均重复测量5次剪切波,取中位数。结果左侧跟腱远、中、近段的剪切波速度之间两两比较均有统计学差异(P值分别为0.016、0.000、0.014);右侧跟腱远、中、近段的剪切波速度之间两两比较均有统计学差异(P值分别为0.000、0.000、0.011);而且跟腱近段SWV最大,跟腱中段SWV次之,跟腱远段SWV最小。左、右侧跟腱在不同部位的SWV均没有统计学差异(P值分别为0.115、0.926、0.213)。男、女性在跟腱远、中、近段的SWV均没有统计学差异。30岁组、30~49岁组、≥50岁组在跟腱远、中、近段的SWV均没有统计学差异。结论 ARFI技术可能是评估正常跟腱弹性特征的可行方法。
[Abstract]:Objective to study the feasibility of acoustic pulse radiography in detecting normal Achilles tendon and to evaluate the elastic characteristics of normal Achilles tendon. Methods 39 healthy volunteers underwent gray-scale ultrasonography, power Doppler ultrasound and ARFI imaging. The Achilles tendon was divided into three parts: proximal segment (muscle-tendon junction), middle segment (2~6cm above the Achilles tendon attachment) and distal segment (calcaneal attachment). Results there were significant differences in shear wave velocities between the left Achilles tendon and the middle and proximal segments (P = 0.016, 0.000, 0.014, P = 0.016, P = 0.014, P = 0.016, P = 0.014, P = 0.016, P = 0.014). There were significant differences in shear wave velocities in the proximal segment (P = 0.000 ~ 0.000 ~ 0.011), and the SWV in the proximal segment of the Achilles tendon was the largest, the SWV in the middle segment of the Achilles tendon was the second, and the SWV in the distal segment of the Achilles tendon was the smallest. There was no significant difference in SWV between left and right Achilles tendon at different sites (P = 0.115 0. 926) and 0. 213% (P < 0. 213). There was no significant difference in SWV between male and female in distal Achilles tendon. There was no significant difference in SWV between 30 and 49 years old group in 30 years old group, and there was no significant difference in SWV in middle and proximal segment in 鈮，
