Validation of shear wave elastography in skeletal muscle.
Skeletal muscle is a very dynamic tissue, thus accurate quantification of skeletal muscle stiffness throughout its functional range is crucial to improve the physical functioning and independence following pathology. Shear wave elastography (SWE) is an ultrasound-based technique that characterizes tissue mechanical properties based on the propagation of remotely induced shear waves. The objecti...
متن کاملShear wave group velocity inversion in MR elastography of human skeletal muscle.
In vivo quantification of the anisotropic shear elasticity of soft tissue is an appealing objective of elastography techniques because elastic anisotropy can potentially provide specific information about structural alterations in diseased tissue. Here a method is introduced and applied to MR elastography (MRE) of skeletal muscle. With this method one can elucidate anisotropy by means of two sh...
متن کاملValidity of Measurement of Shear Modulus by Ultrasound Shear Wave Elastography in Human Pennate Muscle
Ultrasound shear wave elastography is becoming a valuable tool for measuring mechanical properties of individual muscles. Since ultrasound shear wave elastography measures shear modulus along the principal axis of the probe (i.e., along the transverse axis of the imaging plane), the measured shear modulus most accurately represents the mechanical property of the muscle along the fascicle direct...
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 ...
متن کاملclinical application of shear wave elastography in breast masses
results of the 133 breast lesions, 32 were malignant and 101 were benign. in the differentiation of benign and malignant lesions, conventional us resulted in sensitivity of 100 %, specificity of 43.0 %, ppv of 57.1 %, npv of 36.7 %, and accuracy of 100 %. regarding swe, the sensitivity, specificity, ppv, npv, and accuracy values based on emax were 84.4 %, 89.1 %, 71.1 %, 94.7 %, and 88.0 %, res...
