Fatty liver is a condition in which the amount of fat in the liver accounts for more than 5% of the liver's weight. The use of alcohol and alcoholic beverages in Vietnam is quite common, especially among men. It is estimated that 70% of Vietnamese men drink alcohol and 1 in 4 people use alcohol and beer at harmful levels, equivalent to 6 cups of beer per day. As a result, the number of cases of fatty liver caused by alcohol increased rapidly, causing many difficulties for treatment.

Liver ultrasound is the most common imaging technique used to diagnose fatty liver today. Not only helping to detect disease, liver ultrasound also helps evaluate the degree of fatty liver, thereby helping doctors to have effective treatment for each patient.
