Nonalcoholic fatty liver disease (NAFLD) affects approximately a quarter of the human population globally. NAFLD may progress to nonalcoholic steatohepatitis (NASH) in 20% of patients. NASH is a leading cause of liver transplantation as it can contribute to the development of fibrosis, cirrhosis, and hepatocellular carcinoma. Liver biopsy is the current reference standard for diagnosing NAFLD; however, owing to its invasiveness and the possibility of sampling errors, a noninvasive technique is required for assessing hepatic steatosis. Recently, Quantitative US (QUS) techniques have been proposed as noninvasive and objective tools for the detection and grading of hepatic steatosis.

Quantitative fat estimation at Vital Scans and Diagnostics is performed on the premium USG machine Samsung V8 by Quantitative ultrasound (QUS) Technology to assess the steatotic liver changes.
