Shear wave elastography in diffuse thyroid disease [PDF]

Biomedical Papers, 2021
Our aim was to examine the contribution of shear wave elastography to ultrasonographic assessment in diffuse thyroid disease, specifically to evaluate the stiffness of the thyroid gland in diffuse thyroid disease and compare it with healthy controls.A total of 46 patients with diffuse thyroid disease were examined clinically, by conventional ultrasound,

Deep Learning for High Speed Optical Coherence Elastography

, 2020
Mechanical properties of tissue provide valuable information for identifying lesions. One approach to obtain quantitative estimates of elastic properties is shear wave elastography with optical coherence elastography (OCE).

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.

Does shear wave ultrasound independently predict axillary lymph node metastasis in women with invasive breast cancer? [PDF]

, 2013
Shear wave elastography (SWE) shows promise as an adjunct to greyscale ultrasound examination in assessing breast masses. In breast cancer, higher lesion stiffness on SWE has been shown to be associated with features of poor prognosis.

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.
