Our Shear Wave technology provides a quantitative measure and dynamic visual display of tissue stiffness in a variety of clinical settings. Providing you wit

Shear wave elastography relies on the generation of shear waves determined by the displacement of tissues induced by the force of a focused ultrasound beam or by an external push. QElaXto The shear waves are lateral waves, with a motion perpendicular to the direction of the force that has generated them.

Recently introduced on clinical scanners, shear-wave elastography (SWE) is considered to be more objective, quantitative, and reproducible than compression sonoelastography with increasing applications to the musculoskeletal system. Shear wave propagation maps obtained using Transient Elastography VCTE technique in a normal liver (top) and a cirrhotic liver (bottom). The liver stiffness is significantly higher in the cirrhotic liver. Transient Elastography was initially called Time-Resolved Pulse Elastography when it was introduced in the late 1990s. With shear wave elastography (SWE) a quantitative measure of the lesion stiffness is obtained either in a region of interest (ROI), point quantification SWE (pSWE) or pixel-by-pixel using a color map, 2-D SWE. Examples of a benign and malignant lesion are presented in ▶ Fig. 4.2 and ▶ Fig. 4.3.

Abstract: Ultrasound shear wave elastography (SWE) is an emerging technique for characterizing local arterial stiffness - a known indicator for vascular health. Objectives To compare shear-wave speed (SWS) measured by ultrasound-based point shear-wave elastography (pSWE) and MR elastography (MRE) on 8 Dec 2020 In this paper, we propose Plane Wave Elastography (PWE), a novel ultrasound shear wave elastography (SWE) approach. Currently, commercial The value of elastography. Philips shear wave elastography simplifies liver assessment, making obtaining liver stiffness measurements fast and easy.

18 Apr 2018 There are two types of elastography: strain and shear wave elastography. Strain elastography applies compressive force to breast tissue and

This non- MR Shear Wave Elastography. Magnetic resonance elastography (MRE) is a technique used to investigate the stiffness of various body tissues.

5.4.5.2 Shear Wave Elastography SWE is a type of US elastography that uses shear waves to assess tissue elasticity and display it in a quantitative manner. Unlike acoustic compressive waves, which spread in the same direction as the particle compression, the propagation of shear waves proceeds orthogonal to the stimulated displacement.
