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

Comparison of 2-D Shear Wave Elastography and Point Shear Wave Elastography for Assessing Liver Fibrosis [PDF]

Ultrasound in Medicine & Biology, 2021
Progressive liver fibrosis may result in cirrhosis, portal hypertension and increased risk of hepatocellular carcinoma. We performed a meta-analysis to compare liver fibrosis staging in chronic liver disease patients using 2-D shear wave elastography (2-D SWE) and point shear wave elastography (pSWE).

Elastography in the assessment of the Achilles tendon: a systematic review of measurement properties

Journal of Foot and Ankle Research, 2023
Background Managing and rehabilitating Achilles tendinopathy can be difficult, and the results are often unsatisfactory. Currently, clinicians use ultrasonography to diagnose the condition and predict symptom development.

Shear wave elastography in assessment of liver stiffness and prediction of gastro-esophageal varices in patients with liver cirrhosis

The Egyptian Journal of Radiology and Nuclear Medicine, 2019
Background Shear wave elastography is an ultrasound applied technique used to measure tissue stiffness as a result of a disease. So, it can be used to evaluate liver stiffness as a result of liver cirrhosis and could correlate it with esophageal varices.

Validity of measurement of shear modulus by ultrasound shear wave elastography in human pennate muscle. [PDF]

PLoS ONE, 2015
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 ...

Reproducibility of Natural Shear Wave Elastography Measurements [PDF]

Ultrasound in Medicine & Biology, 2019
For the quantification of myocardial function, myocardial stiffness can potentially be measured non-invasively using shear wave elastography. Clinical diagnosis requires high precision. In 10 healthy volunteers, we studied the reproducibility of the measurement of propagation speeds of shear waves induced by aortic and mitral valve closure (AVC, MVC ...

Shear Wave Elastography versus Strain Elastography in Diagnosing Parathyroid Adenomas [PDF]

International Journal of Endocrinology, 2020
Objectives. The aim of the study was to compare elastographic means in parathyroid adenomas, using shear wave elastography and strain elastography. Methods. This prospective study examined 20 consecutive patients diagnosed with primary hyperparathyroidism and parathyroid adenoma, confirmed by biochemical assay, technetium-99 sestamibi scintigraphy, and
