Evaluation of normal and pathological Achilles tendon by real-time shear wave elastography.
Tendinopathy covers a range of several tendon conditions, mostly caused by overuse but at least in Achilles tendon pathology, favored by obesity, diabetes, inflammatory and autoimmune conditions. Subclinical tendon pathology is difficult to diagnose, as magnetic resonance imaging (MRI) examinations are sometimes inconclusive and not cost-effective. Elastography is an ultrasound examination meth...
متن کاملSpatial variations in Achilles tendon shear wave speed.
Supersonic shear imaging (SSI) is an ultrasound imaging modality that can provide insight into tissue mechanics by measuring shear wave propagation speed, a property that depends on tissue elasticity. SSI has previously been used to characterize the increase in Achilles tendon shear wave speed that occurs with loading, an effect attributable to the strain-stiffening behavior of the tissue. Howe...
متن کاملEvaluation of Elastic Stiffness in Healing Achilles Tendon After Surgical Repair of a Tendon Rupture Using In Vivo Ultrasound Shear Wave Elastography
BACKGROUND There has been no published report assessing the mechanical properties of a repaired Achilles tendon after surgery using shear wave elastography (SWE). The aim of this study was to investigate the changes in mechanical properties of the healing Achilles tendon after surgical repair of a tendon rupture using ultrasound SWE and how these changes correlate with tendon function. MATERIAL...
متن کاملShear wave elastography of the supraspinatus muscle and tendon: Repeatability and preliminary findings.
Shear wave elastography (SWE) is a promising tool for estimating musculoskeletal tissue properties, but few studies have rigorously assessed its repeatability and sources of error. The objectives of this study were to assess: (1) the extent to which probe positioning error and human user error influence measurement accuracy, (2) intra-user, inter-user, and day-to-day repeatability, and (3) the ...
متن کاملMeasuring shear-wave speed with point shear-wave elastography and MR elastography: a phantom study
OBJECTIVES To compare shear-wave speed (SWS) measured by ultrasound-based point shear-wave elastography (pSWE) and MR elastography (MRE) on phantoms with a known shear modulus, and to assess method validity and variability. METHODS 5 homogeneous phantoms of different stiffnesses were made. Shear modulus was measured by a rheometer, and this value was used as the standard. 10 SWS measurements ...
