Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease
with an estimated prevalence of up to 30% in the whole population. Liver steatosis is an important histological feature of NAFLD
which can lead to liver fibrosis or cirrhosis
and even increase the risk of hepatocellular carcinoma as the disease progresses. The gold standard for quantitatively evaluating liver steatosis is liver biopsy
but it is invasive. Imaging technology enables non-invasive and quantitative assessment of liver fat. The guidelines recommend ultrasound as the first-line imaging diagnostic method for NAFLD
which has the advantages of being convenient
real-time
non-invasive and visualization. Recently
quantitative ultrasonic technologies have emerged
and the technical parameters include attenuation coefficient
backscatter coefficient
and sound velocity. However
there is limited evidence for the clinical application of various new ultrasound technologies
and a large amount of research is needed to explore and optimizeoperational methods to reduce the impact factors on measurement. This review introduced the change in the name of fatty liver disease
the current status of clinical diagnosis
the interpretation of international consensus from the World Federation for Ultrasound in Medicine and Biology
and introduced representative quantitative ultrasound techniques based on attenuation coefficient
with their diagnostic value in the detection of hepatic steatosis. Moreover
this review evaluated diagnosis
monitoring
and prediction by ultrasound quantitative detection technology for the application of hepatic steatosis.
