The Role of Endoscopic Ultrasound-Guided Shear Wave Elastography in Pancreatic Diseases

Diagnostics
Elastography is a non-invasive imaging modality that has been developed for the evaluation of the stiffness of various organs. It is categorized into two main types: strain elastography and shear wave elastography.

An investigation of the functional significance of the pyramidalis muscle using shear wave elastography

Journal of Anatomy, EarlyView.
The 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 ...

Performance Study of a Torsional Wave Sensor and Cervical Tissue Characterization

Sensors, 2017
A novel torsional wave sensor designed to characterize mechanical properties of soft tissues is presented in this work. Elastography is a widely used technique since the 1990s to map tissue stiffness. Moreover, quantitative elastography uses the velocity

Single‐Breathhold 3D MR Elastography in the Liver, With Simultaneous R2* and PDFF Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 682-697, August 2026.
Purpose To develop a sequence for the rapid acquisition of MR elastography (MRE) parameters in 3D, with simultaneous measurement of proton‐density fat fraction (PDFF) and R2* for multiparametric assessment of liver disease. Methods The proposed sequence uses an interleaved motion‐encoding scheme to acquire 3D volumes of all motion encodings and wave ...

Chronic Liver Disease: Assessing Inflammation and Fibrosis Using Three‐Dimensional MR Elastography With Same‐Day Biopsy in a Prospective Cohort

Journal of Magnetic Resonance Imaging, Volume 64, Issue 1, Page 306-319, July 2026.
ABSTRACT Background Three‐dimensional (3D) MR elastography (MRE) derives viscoelastic parameters that may reflect inflammation, but their frequency dependence and the influence of steatosis on inflammation grading and fibrosis staging remain unclear. Purpose To investigate 3D multifrequency MRE for assessing hepatic inflammation, fibrosis stage across ...

Two-Dimensional Shear-Wave Elastography of the Thyroid in Clinically Healthy Dogs in Different Age Groups

Animals
The thyroid of dogs has not been extensively studied in 2D shear-wave elastography, making it challenging to apply this technique in the diagnosis of thyroid diseases in a non-invasive manner.

Shear Wave Elastography to Assess Respiratory Muscle Function in Congenital Myopathies

Muscle &Nerve, Volume 74, Issue 1, Page 103-110, July 2026.
ABSTRACT Introduction/Aims Respiratory muscle dysfunction is prevalent in congenital myopathies and often leads to respiratory failure. Ultrasound shear wave elastography (SWE) measures tissue elasticity and has been proposed as an alternative to invasive measures of respiratory muscle contractility.
