Commentary
Supersonic shear imaging (SSI) is a relatively new technique to measure the elasticity of target tissues based on the shear wave propagation. In this study, J. Yang et al. aimed to evaluate the value of SSI in discriminating NASH from NAFLD, NASH with fibrosis, and the normal liver, as well as the relationship between various NAFLD pathologic or biochemical findings and SSI liver elasticity.
Rabbits with NAFLD of different degrees were subjected to SSI for liver elasticity measurement. The results indicate that SSI can effectively identify nonfibrotic NASH in rabbits based on the difference in liver elasticity and the difference is related to the various pathologic changes, including fibrosis, inflammation, steatosis, and ballooning degeneration.
