Measuring shear-wave speed with point shear-wave elastography and MR elastography: a phantom study [PDF]
BMJ Open, 2017 ObjectivesTo 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.Methods5 homogeneous phantoms of different stiffnesses were made. Shear modulus was measured by a rheometer, and this value was used

An investigation of the functional significance of the pyramidalis muscle using shear wave elastography. [PDF]
J AnatThe pyramidalis (Py) is a small triangular‐shaped anterior abdominal wall muscle, the function of which remains uncertain. We used shear wave elastography to test the hypothesis that Py contributes to stiffness of the linea alba. Our results indicate that Py contraction results in a significant increase in LA stiffness, supporting the previously ...

Future of breast elastography [PDF]
Ultrasonography, 2019 Both strain elastography and shear wave elastography have been shown to have high sensitivity and specificity for characterizing breast lesions as benign or malignant. Training is important for both strain and shear wave elastography.

Viscoelasticity Imaging of Biological Tissues and Single Cells Using Shear Wave Propagation
Frontiers in Physics, 2021 Changes in biomechanical properties of biological soft tissues are often associated with physiological dysfunctions. Since biological soft tissues are hydrated, viscoelasticity is likely suitable to represent its solid-like behavior using elasticity and ...

Evaluation of liver stiffness measurement–based scores in liver transplantation recipients
Liver Transplantation, EarlyView., 2022 Abstract Combining bioclinical parameters with liver stiffness measurement (LSM) has improved the diagnostic performance of vibration‐controlled transient elastography (VCTE) for detection of advanced fibrosis in patients with chronic liver disease. However, this approach has not yet been tested in liver transplantation (LT) recipients.

Characterization of soft tissue tumours with ultrasound, shear wave elastography and MRI [PDF]
, 2020 OBJECTIVE: To predict accurately whether a soft tissue mass was benign or malignant and to characterize its type using ultrasound, shear wave elastography and MRI. We hypothesized that with the addition of shear wave elastography, it would be possible to

Reproducibility of shear wave elastography (SWE) in patients with chronic liver disease. [PDF]
PLoS ONE, 2017 The presence of significant fibrosis is an indicator for liver disease staging and prognosis. The aim of the study was to determine reproducibility of real-time shear wave elastography using a hepatic biopsy as the reference standard to identify patients
