[Ultrasound technologies' new clinical application for chronic liver diseases]

Chronic liver disease and its complications impose a heavy burden，and the limits of liver biopsy tests have rendered non-invasive assessment an urgent clinical need. Multiple novel parameters，such as elasticity，viscosity，fat quantification，and micro-flow imaging，have been established as reliable methods for staging liver fibrosis，monitoring inflammatory activity，and quantifying steatosis，providing considerable potential for diagnosis，disease monitoring，and prognostic management of chronic liver diseases via ultrasonically technology at an early stage. Challenges such as the non-universal nature of diagnostic thresholds，interference from confounding factors，and a lack of technical standardization remain，despite the considerable value of each technology. Therefore，the integration of multiple parameters and artificial intelligence models may be a breakthrough direction in the future.
