Hepatic steatosis is het abnormal and excessive accumulation of triglycerides in the liver and is a hallmark of non-alcoholic fatty liver disease (NAFLD). The aim of this study was to determine differences in in vivo lipid metabolism in steatotic livers of rats on different high-fat diets using 1H MRS with 13C editing in combination with the oral administration of 13C-labeled lipids. Animals on a high-fat diet developed liver steatosis accompanied by a significantly reduced lipid turnover in the liver.
