BACKGROUND Real-time elastography (RTE) and shear wave elastography (SWE) are noninvasive and easily available imaging techniques that measure the tissue strain, and it has been reported that the sensitivity and the specificity of elastography were better in differentiating between benign and malignant thyroid nodules than conventional technologies. METHODS Relevant articles were searched in ...

Over the last years, more and more sensor systems emerged that can not only be accessed but also controlled and configured using the Internet. This trend allows mobile applications that rely on sensor data; however, the access and configuration of sensor systems is a tedious task. As many sensor manufacturers implement their own protocols, there are many communication protocols. Although unifyi...

Shear wave elastography (SWE) is an emerging technique for measuring biological tissue stiffness. However, the application of SWE in thin layer tissues is limited by bias due to the influence of geometry on measured shear wave speed. In this study, we investigated the bias of Young's modulus measured by SWE in thin layer gelatin-agar phantoms, and compared the result with finite element method ...

results of the 133 breast lesions, 32 were malignant and 101 were benign. in the differentiation of benign and malignant lesions, conventional us resulted in sensitivity of 100 %, specificity of 43.0 %, ppv of 57.1 %, npv of 36.7 %, and accuracy of 100 %. regarding swe, the sensitivity, specificity, ppv, npv, and accuracy values based on emax were 84.4 %, 89.1 %, 71.1 %, 94.7 %, and 88.0 %, res...

This paper provides a summary of the work carried out by BT Research over the last three years while investigating Generic Sensor Network Architectures and Sensor Web Enablement (SWE). An overview of SWE and Complex Event Processing (CEP) is provided. In addition, the SAPHE and BRIDGE projects are discussed, which have served as case studies for the application of SWE specifications or CEP tech...

BACKGROUND Approximately 10-20 million Americans have been clinically diagnosed with thyroid nodules. Shear wave elastography (SWE) and real-time elastography (RTE) are two primary forms of elastography for identifying the status of thyroid nodules. The aim of this study is to assess the performance of RTE and SWE in identifying malignant thyroid nodules. METHODS Relevant articles were system...

AIM To assess the accuracy of shear wave elastography (SWE) alone and in combination with aminotransferase platelet ratio index (APRI) score in the staging of liver fibrosis. METHODS A multicenter prospective study was conducted to assess the accuracy of SWE (medians) and APRI to predict biopsy results. The analysis focused on distinguishing the different stages of liver disease, namely, F0 f...

Subcritical water extraction (SWE) of Inonotus Obliquus polysaccharides (IOP) was investigated using response surface methodology (RSM) with a design by Box–Behnken design (BBD). Results showed that the optimum SWE conditions for IOP production were as follows: extraction temperature 194°C, residence time 5.36 min and liquidsolid ratio 53 mL/g, yielding 168.80 ± 0.59 mg/g of IOP, which was in c...

Radiofrequency ablation (RFA) is a minimally invasive method for treating tumors. Shear wave elastography (SWE) has been widely applied in evaluating tissue stiffness and final ablation size after RFA. However, the usefulness of periablation SWE imaging in assessing RFA remains unclear. Therefore, this study investigated the correlation between periablation SWE imaging and final ablation size. ...
