Table 1 Scoring protocol for hepatic steatosis by ultrasonography

From: Noninvasive tool for the diagnosis of NAFLD in association with atherosclerotic cardiovascular risk

U/S features Score Definition
Liver echotexture (ECO) 0 Normal: echo level of the liver parenchyma is homogenous and no difference in contrast between liver and kidney parenchyma
1 Mild fatty change: slightly increase in echo pattern of the liver
2 Moderate fatty change: intermediate between scores 1 and 3
3 Severe fatty change: gross discrepancy of the increased hepatic to renal cortical echogenicity
Echo penetration and visibility of diaphragm (DIA-VIS) 0 Normal: liver structure is clearly defined from the surface of the diaphragm. The outline of the diaphragm is clearly visualized
1 Mild fatty change: mild attenuation of sound beam through the liver
2 Moderate fatty change: intermediate between scores 1 and 3
3 Sever fatty change: marked attenuation of sound beam through the liver. The diaphragm is not visualized
Clarity of liver blood vessel structures (VAS) 0 Normal: vessel wall and lumen of the vessel can be clearly visualized
1 Mild fatty change: slightly decreased definition of portal venule walls
2 Moderate fatty change: intermediate between scores 1 and 3
3 Sever fatty change: only the main portal veins can be visualized with the absence of all smaller portal venule walls
