Figure 1 Bedside ultrasound image displaying sonographic characteristics on non-alcoholic fatty liver disease. Attenuation of image (green arrow), diffuse echogenicity, uniform heterogeneous liver, thick subcutaneous depth (yellow arrow), and enlarged liver filling of the entire field as described by Riley et al[9].

The algorithm illustrates the use of ultrasound in reducing the need for liver biopsy in the diagnosis of non-alcoholic fatty liver disease.
