Shear wave elastography with a new reliability indicator
Non-invasive methods for liver stiffness assessment have been introduced over recent years. Of these, two main methods for estimating liver fibrosis using ultrasound elastography have become established in clinical practice: shear wave elastography and quasi-static or strain elastography. Shear waves are waves with a motion perpendicular (lateral) to the direction of the generating force. Shear...
متن کاملA Finite Element Model of Shear Wave Propagation Induced By an Acoustic Radiation Force Impulse
Shear wave elastography is an innovative technique that employs one conventional focused ultrasound beam to induce shear waves and another to detect them. The final quantitative elasticity image is presented as a colour map overlaying the B-mode image. This new technique is used in combination with traditional ultrasound imaging in order to improve the specificity of distinguishing malignant an...
متن کاملInability of shear-wave elastography to distinguish malignant from benign prostate tissue – a comparison of biopsy, whole-mount sectioning and shear-wave elastography
AIM This study was designed to assess the possible usefulness of shear-wave elastography in differentiating between benign and malignant tissue in prostate neoplasia. PATIENTS AND METHODS A total of 120 prostate tissue samples were obtained from 10 patients treated by radical prostatectomy and investigated pre-operatively by ultrasound elastography followed by directed biopsy. After resection...
متن کاملEvaluation of the diagnostic function of shear wave elastography in the differentiation of malignant and benign breast masses and its relationship with histological factors
Background: Shear wave elastography (SWE) estimates the stiffness of a mass based on the velocity of shear wave propagation by sound waves. Due to higher cell density and angiogenesis, malignant masses have higher stiffness than benign ones. Methods: The present study was a prospective study and was performed on patients who were referred to Ahvaz Golestan Hospital with breast mass during Marc...
متن کاملIntra-Individual Comparison between 2-D Shear Wave Elastography (GE System) and Virtual Touch Tissue Quantification (Siemens System) in Grading Liver Fibrosis.
Ultrasound-based shear wave elastography (SWE) has recently gained substantial attention for non-invasive assessment of liver fibrosis. The purpose of this study was to perform an intra-individual comparison between 2-D shear wave elastography (2-D-SWE with a GE system) and Virtual Touch Tissue Quantification (VTTQ with a Siemens system) to assess whether these can be used interchangeably to gr...
