Ultrasonographic diagnosis of nonalcoholic steatohepatitis based on the quantitative evaluation of the ultrasound beam behavior into the liver

Ultrasonography is a simple method in diagnosing nonalcoholic steatohepatitis (NASH), providing useful information, but it is subjective and does not accurately differentiate between steatosis grades. The computerized processing of the data that comprises the ultrasonic image might transform ultrasonography into an objective examination. We aim to study the performance of the quantitative evaluation of the ultrasound beam behavior into the liver in diagnosing NASH and in establishing the fatty load grade.
