ABSTRACT
The invasiveness and sampling errors of liver biopsies have prompted the development of diverse non-invasive methods for evaluating liver stiffness. Recently, shear wave-based ultrasound elastography, such as transient elastography (TE), acoustic radiation force impulse (ARFI) imaging and supersonic shear imaging (SSI), as well as quasi-static elastography, such as real-time tissue elastography, have been introduced as noninvasive techniques for evaluating liver stiffness. This editorial reviews each elastographic technique in terms of the principle and clinical applications for the liver diseases.
