What happens to the echogenicity of the liver parenchyma and vascular pattern in case of fatty liver infiltration?

• The vascular pattern becomes 'poor' and the echogenicity of the liver parenchyma increases

• The vascular pattern is clearly visualized, with mixed echogenicity

• The echogenicity is decreased, and the vascular pattern is 'poor'

• The echogenicity remains unchanged, with a clear vascular pattern
