WebHepatic sinusoidal obstruction syndrome (SOS), also known as veno-occlusive disease (VOD) can be a life-threatening complication after hematopoietic stem cell transplantation (HSCT). Diagnosis is often difficult and traditionally based on clinical parameters. Shear wave elastography (SWE) is a modern non-invasive liver stiffness measurement … WebJan 8, 2024 · Elastosonography is based on the emission of short-lived (0.03–0.4 ms) high-energy acoustic pulses generated by the probe, which induce a small amount of local displacement (1–20 μm) in the tissue. The so-called “shear waves” are generated following that displacement, which can be detected by the probe.
WebSep 6, 2024 · Shear wave elastography is an ultrasound applied technique used to measure tissue stiffness as a result of a disease. So, it can be used to evaluate liver stiffness as a result of liver cirrhosis and could correlate it with esophageal varices. The purpose of this study was to evaluate the efficiency of shear wave elastography for assessment of liver … WebNov 11, 2024 · Ultrasound elastography, also called as sono-elastography, is a modern evolutionary method of sonographic imaging.Techniques include shear wave …
WebJan 1, 2024 · The other type is shear wave elastography (SWE), where a probe-induced pulse propagates through the tissue of interest waves in a shear manner and presented in kilopascals (kPa, Young modulus). One important advantage of SWE is quantitative results. The other advantage is reproducibility and being less operator-dependent than strain type. WebJul 23, 2024 · 2D shear wave elastography is a technique embedded in ultrasound machines which allows the interrogation of the tissue by acoustic radiation force impulses induced into the tissues by focused ultrasonic beams and captures the propagation of resulting shear waves in real time.
WebMar 11, 2024 · Shear wave elastography (SWE) relies on the generation and tracking of coherent shear waves to image the tissue's shear elasticity. Recent technological developments have allowed SWE to be implemented in commercial ultrasound and magnetic resonance imaging systems, quickly becoming a new imaging modality in medicine and …
