Background and aims: Currently, the golden standard in Nonalcoholic Steatohepatitis (NASH) evaluation is liver biopsy. Ultrasonography (US) is subjective, it cannot state precisely the fat content degree and cannot make a difference between simple steatosis and NASH. We try to determine if is possible to discriminate between healthy and NASH patients and to assess NASH grade by using computerized techniques of ultrasonic image processing (CTUIP). Methods: 54 NASH patients confirmed by liver biopsy according to Brunt score (1-mild, 2-moderate and 3-severe) and 20 healthy patients were analyzed. Fibrosis stage (Me…
