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. Its major consequence is increasing deposition of fibrous tissue within the liver leading to the development of cirrhosis with its consequences of portal hypertension, hepatic insufficiency, and hepatocellular carcinoma.

Shear-wave elastography (SWE) is a new technique for measuring the stiffness of biological tissues [4,7]. It can be used to decrease the high false-positive rate of B-mode US by increasing specificity [8-10]. SWE introduces stress force into the mass and induces shear in the tissue [11]. The acoustic radiation force is generated Shear wave elastography provides information regarding elasticity of shear wave, which is calculated by shear wave speed, as well as dispersion slope of shear wave, which reflects the frequency dependence of both speed and attenuation of shear waves in the viscous component.

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. Transient elastography (TE) is a non-imaging elastographic technique, while point shear wave (p-SWE) and 2D-SWE combine imaging with elastography. The evidence at this time suggests that p-SWE is as accurate as but more reliable than TE, while 2D-SWE is more accurate than TE. Shear wave-based elastography When an ARFI push pulse is sent through tissue, the pulse generates lateral shear waves in the tissue. The speed of the shear waves varies depending on tissue stiffness and can be measured as part of a complementary elastography technique. In Gaucher disease the median stiffness of the spleen as assessed by transient elastography (TE) and shear wave elastography (SWE) was 35KPa and 22KPa respectively in contrast to the median stiffness of healthy controls (16.95 and 17.5KPa, p=0.0028 and p=0.0002, respectively) and of patients with cirrhosis (45KPa and 34.5KPa, p=0.015 and p<0 2021-01-20 · Liver stiffness measurement (LSM) by transient elastography (TE), point shear wave elastography (p-SWE) or two-dimensional SWE (2D-SWE) is an established non-invasive technique to assess significant fibrosis in patients with chronic liver disease.7–13 Moreover, it has proven to be a useful surrogate marker to diagnose clinically significant shear wave elastography in breast clinical applications (Figure 6). Displaying side-by-side strain elastography and ElastQ Imaging 6 Both strain and shear wave elastography techniques help to further characterize breast lesions.

Real-time Monitoring of High Intensity Focused Ultrasound
13-16, 23, 24 Elasticity is Shear wave elastography involves the following processes: generation of shear waves in tissue by an acoustic radiation force, detection of the propagation of the induced shear waves, and processing of the shear waves to create elastograms, which are quantitative maps of tissue elasticity [6,7]. All subjects underwent same-day transient elastography (FibroScan), 2-dimensional shear wave elastography (Supersonic Aixplorer), and liver biopsy after an overnight fast. RESULTS: Transient elastography and 2-dimensional shear wave elastography identified subjects in each group with significant fibrosis (Ishak score ≥3) and cirrhosis (Ishak score ≥5) with high accuracy (area under the curve ≥0.92). 2019-02-23 · 2. Point shear-wave elastography: basic principles. pSWE is a type of SWE in which tissue stimulation is performed at a certain depth by an acoustic radiation force impulse generated by the transducer (ARFI technology), which generates shear waves that propagate into the tissue, perpendicularly on the axis of the initial pulse.
