PURPOSE: To evaluate transient ShearWave elastography of the normal Achilles' tendon.


PATIENTS AND METHODS: The Achilles' tendon of 30 normal subjects were prospectively assessed using a Rubi V1Sq prototype (Supersonic Imagine). Quantitative elastography maps displayed in kilopascals with a scale of 0 to 600kPa were generated from transverse and longitudinal images at 3 different levels of plantar flexion. Subgroups were compared and analyzed based on proven or suspected variation factors (age, gender, level of physical activity).


RESULTS: On sagittal images, mean elasticity was 104±46kPa during extension, 464±144kPa in neutral position and 410±196kPa during maximum dorsiflexion. There was significant increase in elasticity when the Achilles' tendon was maximally stretched (p<0.01). The intra-individual correlation between right and left tendons during ankle extension was good (Pearson Coefficient 0.8; p<0.01). Finally, physically active subjects showed significantly greater elasticity than non-active subjects (p<0.05).


CONCLUSION: Transient ShearWave elastography of the Achilles' tendon is a simple technique that provides real-time information about tissue elasticity.


目的:正常なアキレス腱の一過性ShearWave elastographyを評価すること。

患者と方法:30人の正常被験者のアキレス腱は、Rubi V1Sq原型(超音波は想像する)を使用して、前向きに評価された。

アキレス腱が最大限伸ばされた(p < 0.01)とき、弾力の有意の増加があった。
足首関節牽引の間の左右の腱間の個人内相関は、良好だった(ピアソン係数0.8; p < 0.01)。
最後に、物理的に、能動主語は非活動的な被験者(p < 0.05)より有意に大きな弾力を示した。

結論アキレス腱の一過性ShearWave elastographyは、組織弾力に関するリアルタイム情報を提供する単純な技術である。
