Novel multi-parametric diagnosis of non-alcoholic fatty liver disease using ultrasonography, body mass index, and Fib-4 index

Figure 2 Flowchart of the study. A total of 126 patients who were diagnosed with fatty liver based on abdominal ultrasound and in whom shear wave elastography, shear wave dispersion, and attenuation imaging were measured during the period of this study were entered in the study. Of them, 7 patients with an alcohol intake history of 20 g ethanol/d or more, 3 with hepatitis B, 3 with hepatitis C, and 4 with autoimmune hepatitis or primary biliary cholangitis were excluded. In addition, 1 patient with drug-induced liver injury and 1 patient with cholangitis were excluded, bringing the final number of subjects in this investigation to 107. HBV: Hepatitis B virus; HCV: Hepatitis C virus; AIH: Autoimmune hepatitis; PBC: Primary biliary cholangitis; NAFLD: Non-alcoholic fatty liver disease.
