目的：探讨定量剪切波弹性成像技术评价跟腱功能完整性的可行性，并总结跟腱断裂后与正常对照的弹性变化。方法：应用剪切波弹性成像结合线阵探头(4~15 MHz)对36例正常跟腱和14例跟腱断裂进行检测。结果：正常跟腱平均+/-SD为291.91+/-4.38kPA(注意正常跟腱存在饱和测量现象，实际为-300kPA)，而断裂跟腱的弹性值为56.48+/-68.59kPa.与健康志愿者的结果相比，差异有统计学意义(P=0.006)。结论：我们的结果表明，剪切波弹性成像是一种有价值的工具，可以为评估跟腱功能提供补充的生物力学信息。
Objectives-The purpose of this study was to investigate the feasibility of using quantitative shear wave elastography for assessing the functional integrity of the Achilles tendon and to summarize the changes in elasticity of ruptured Achilles tendons in comparison with normal controls.Methods-Thirty-six normal and 14 ruptured Achilles tendons were examined with shear wave elastography coupled with a linear array transducer (4-15 MHz). The elasticity value value of each Achilles tendon in a longitudinal view was measured.Results-The mean elasticity value +/- SD for the normal Achilles tendons was 291.91 +/- 4.38kPa (note that there are saturated measurement phenomena for the normal Achilles tendon, so the actual value will be >300 kPa), whereas the ruptured Achilles tendons had an elasticity value of 56.48 +/- 68.59 kPa. A statistically significant difference was found in relation to the findings in healthy volunteers (P = .006).Conclusions-Our results suggest that shear wave elastography is a valuable tool that can provide complementary biomechanical information for evaluating the function of the Achilles tendon.
