Shear wave elastography for intracranial epidermoid tumors
Clinical Neurology and Neurosurgery, 2021Ultrasound elastography (USE) is a novel technique that assesses the mechanical properties of body tissues in real time. Based on elasticity measurements, USE enables the differentiation of tumor tissue from surrounding normal tissue.We aimed to evaluate an intraoperative SWE technique for differentiating tumor tissue (epidermoid cyst) from the ...

An Artifact in Supersonic Shear Wave Elastography
Ultrasound in Medicine & Biology, 2017Supersonic shear wave elastography is a novel ultrasound technology that allows objective evaluation of soft tissue stiffness. The purpose of this study is to report an artifact in supersonic shear wave elastography that may strongly affect the accuracy and quality of the measurement of soft tissue stiffness, and to step-by-step describe how the ...

Shear wave elastography in ophthalmic diagnosis
Journal Français d'Ophtalmologie, 2019Shear wave elastography (SWE) is a non-invasive diagnostic imaging technique that maps the elastic properties of tissues. This modality is being increasingly developed in other areas of medicine, offering a new type of high-quality ultrasound examination, since it increases specificity and thus improves diagnostic accuracy.

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2012
The study of new tissue mechanical properties such as shear nonlinearity could lead to better tissue characterization and clinical diagnosis. This work proposes a method combining static elastography and shear wave elastography to derive the nonlinear shear modulus by applying the acoustoelasticity theory in quasi-incompressible soft solids.

Shear Wave Imaging of Breast Tissue by Color Doppler Shear Wave Elastography
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2017Shear wave elastography is a distinctive method to access the viscoelastic characteristic of the soft tissue that is difficult to obtain by other imaging modalities. This paper proposes a novel shear wave elastography [color Doppler shear wave imaging (CD SWI)] for breast tissue.

Shear wave elastography for muscle biomechanics
The Journal of the Acoustical Society of America, 2021In vivo muscle biomechanical properties are classically deduced from inverse dynamics or measures of joint torque performed using ergometers. However, this provide information about the combined behavior of several structures. Thus, it is complicated to isolate the behavior of an individual muscle. Ultrasound elastography techniques have been developed

Two Dimensional Shear Wave Elastography/Supersonic Shear Imaging
2020Ultrasound imaging provides both morphological (gray-scale images) and functional imaging (flow imaging) of soft tissue. Recently, a new dimension has been added to ultrasound systems: imaging of tissue mechanical characteristics. ShearWave™ Elastography (2D-SWE) was the first ultrasound imaging mode to provide quantitative tissue elasticity images of ...
