Purpose

The prevalence of steatosis in patients with chronic liver disease is growing worldwide [2].

Hepatic fibrosis staging has been used as a prognostic factor by clinicians to measure clinical outcomes and as an index to establish therapeutic plans in patients with chronic liver disease (CLD) [1;2].

Multiparametric approach using the new ultrasound technique as attenuation imaging (ATI) and dispersion imaging for quantitative evaluation of steatosis and viscosity in cases of diffuse chronic diseases, helps to detect the changes without using the invasive methods. [3;4;5].

The aim of the study is to analyze the diagnostic value of liver ultrasound attenuation imaging (ATI) and dispersion imaging in quantitative evaluation of steatosis and viscosity in cases of diffuse chronic diseases.
