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.

On the effects of reflected waves in transient shear wave elastography
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2011In recent years, novel quantitative techniques have been developed to provide noninvasive and quantitative stiffness images based on shear wave propagation. Using radiation force and ultrafast ultrasound imaging, the supersonic shear imaging technique allows one to remotely generate and follow a transient plane shear wave propagating in vivo in real ...

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 Ultrasound Elastography of the Prostate
Ultrasound Quarterly, 2012This prospective study was to evaluate shear wave elastography (SWE) in the detection of prostate cancer (PC).Patients scheduled for a transrectal ultrasound (TRUS) biopsy of the prostate because of elevated prostate-specific antigen levels or abnormal digital rectal examination result underwent a standard TRUS and SWE.

Shear-Wave Elastography in the Characterization of Pleural Effusions
Ultrasound Quarterly, 2019Abstract The aim of the study was to investigate the efficacy of shear-wave elastography (SWE) in the differentiation of transudative and exudative pleural effusions. This monocentric study comprised 60 cases (17 transudative, 43 exudative).Transthoracic SWE was performed in 60 cases for whom to use thoracentesis for the pleural fluid ...

Regularized tracking of shear-wave in ultrasound elastography
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017Ultrasound elastography involves imaging tissue while it undergoes deformation and inferring its mechanical properties from the deformation pattern. The initial deformation in the tissue is typically induced through an external mechanical force, for example, by exerting a slight pressure using an ultrasound probe or by applying an acoustic radiation ...

Shear Wave Elastography for Evaluation of Liver Fibrosis
Journal of Ultrasound in Medicine, 2014The prognosis and management of chronic viral hepatitis mainly depend on the extent of liver fibrosis, particularly in chronic hepatitis C. Liver histologic analysis is still considered the reference standard in the assessment of liver fibrosis despite the interobserver and interobserver variability in staging and some morbidity and mortality risks ...
