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.

Ingår i avhandling. 1. Ultrasound based shear wave elastography of the liver: a non-invasive method for evaluation of liver disease 

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.

A high- speed acquisition is necessary to capture the shear wave as it moves at a speed in the order of 1 to 10 m/s.

Shear-wave images are automatically coregistered with standard B-mode images to provide quantitative color elastograms with anatomic specificity. Shear waves propagate faster through stiffer contracted tissue, as well as along the long axis of tendon and muscle.

Noninvasive Assessment of Myocardial Stiffness by 2D-SWE Ultrasound Technique (Bidimensional Shear Wave Elastography) in Patients With Transthyretin 

In the past 2 decades, sonoelastography has been progressively used as a tool to help evaluate soft-tissue elasticity and add to information obtained with conventional gray-scale and Doppler ultrasonographic techniques. Recently introduced on clinical scanners, shear-wave Shear wave elastography is a developing variation of ultrasound imaging. The concept is similar to strain elastography, but instead of using transducer pressure to compare a shift in an ultrasound A-line (thereby measuring changes in strain), a higher intensity pulse is transmitted to produce shear waves, which extend laterally from the insonated Shear wave liver elastography Chronic liver disease is a substantial world-wide problem.
