Non-Alcoholic Fatty Liver Disease (NAFLD) is an umbrella term that encompasses a spectrum of disorders, such as fat deposits in the liver, steatohepatitis, liver fibrosis, and cirrhosis, which can be found during an ultrasound and liver biopsy and are neither caused by alcohol consumption nor accompanied by other disorders. Recent figures show that the prevalence of NAFLD in Asia and the USA is approximately 30%, while its global prevalence is approximately 25% [1]. Fat deposits in the liver can increase the chances of triggering inflammatory responses and also lead to liver fibrosis. Hence, it is important to continuously monitor the liver once the patient is diagnosed with fatty liver disease. Ultrasound in patients with fatty liver typically shows increased echogenicity of the liver parenchyma relative to the right kidney cortex due to accumulation of neutral lipids in hepatocytes. Moreover, technologies that quantify attenuation of ultrasound signals generated from inside the liver, as well as changes in the scattering properties, which may occur depending on the severity of fatty liver, have been introduced and are currently being studied.
