The description of the Quantitative Elastography QElaXto (Esaote S.p.A.,
Italy) point Shear Wave Elastography (pSWE) technology and the illustration of the technical and practical aspects for a correct procedure of tissue stiffness quantification of the liver.
pSWE delivers a quantitative measure of tissue stiffness (expressed in Shear Wave propagation velocity or deduced Young Modulus in KPa) for a small tissue sample.
pSWE is based on a perturbation and a reading phase.
Non-invasive methods such as pSWE can now be used instead of liver biopsy in patients with chronic hepatitis C,
to assess liver disease severity (fibrosis) before therapy at a safe level of predictability.
What pSWE is about
Point Shear Wave Elastography (pSWE) technology is characterized by the generation of a...
