Imaging cannot clearly distinguish between fatty liver and NASH or predict the degree of fibrosis. Benign steatosis may be either focal or diffuse, whereas steatohepatitis is typically diffuse. However, noninvasive studies such as ultrasonography, CT scan, and MRI have been used increasingly to detect fatty liver. Due to its lower cost and widespread availability, liver ultrasonography is perhaps the most popular modality used in the diagnosis of NAFLD.

The diagnosis of NASH involves an assessment of multiple independent features. The minimal criteria for the diagnosis of NASH that are generally accepted are steatosis, ballooning degeneration, and lobular inflammation.

Systematic screening of family members of patients with NAFLD is currently not recommended.
