Non alcohol fatty liver diseases (NAFLD) is the most common chronic liver diseases and the early diagnosis is essential to prevent complications. There is need for development of noninvasive tool to determine the severity. Non alcoholic fatty changes in liver may be present in obese and diabetic patients and thus will alter the management. Since ultrasound is noninvasive technique for the diagnosis of fatty liver diseases in comparison with liver biopsy. While performing ultrasound abdomen, liver echogenicity can be homogenous and normal, slightly diffused increased echogenicity or markedly increased echogenicity (alteredtexture changes multiple, nodular or irregular hyperechogenic lesions) with poor or non-visulization of intrahepatic vessels. This was the method for grading of fatty changes in liver and also compared the size. As determined the echogenicity and increase in size were found to have direct relationship..In this article the type of echogenicity changes along with variation in size of liver were recorded. Age did not have much significance, but it was seen that greater number of female obese patients.
