Strain Ratio as a Quantification Tool in Strain Imaging [PDF]

Applied Sciences, 2018
Ultrasound-based strain imaging is available in several ultrasound (US) scanners. Strain ratio (SR) can be used to quantify the strain recorded simultaneously in two different user-selected areas, ideally exposed to the same amount of stress. The aim of this study was to evaluate SR variability when assessed in an in-vitro setup with a tissue-mimicking

Comparison of Muscle to Nodule Strain Ratio Elastography with Parenchyma to Nodule Strain Ratio Elastography in Suspicious Thyroid Nodules

Diyala Journal of Medicine
Background: Ultrasound elastography (USE) is a non-invasive technique for distinguishing benign from malignant thyroid nodules. It uses strain ratio to determine thyroid nodular stiffness, however it has limitations when no normal thyroid tissue is present.

Diagnostic utility of strain elastography in assessing median nerve changes among rheumatoid arthritis patients without symptoms of carpal tunnel syndrome: An analytical observational study

Indian Journal of Rheumatology, 2022
Background: The elastography measurements in rheumatoid arthritis (RA) without carpal tunnel syndrome (CTS) are the least studied. Hence, the present study assessed the role of elastography in detecting the median nerve changes before the development of ...

The Elastic Strain Ratio, the Lüders Strain Ratio and theEvolution of r‐Value During Tensile Deformation [PDF]

Texture, Stress, and Microstructure, 1992
The elastic counterpart of the plastic strain ratio is derived from ultrasonic data measured on twenty commercial deep drawing steels. It is shown that the observed variations in plastic r are related to the evolution of texture, and are not affected either by the elastic range of deformation or by the propagation of Lüders bands.
