Non-alcoholic fatty liver disease affects about 30% of the general population and is the leading cause of chronic liver disease in the United States. The gold standard for diagnosis and monitoring is by an invasive biopsy, which has several limitations. MRI methods based on multi-echo fat-water separation can provide non-invasive quantification of fat in the entire liver. In this work, we have developed a free-breathing multi-echo 3D stack-of-stars MRI technique that can produce fat-water separated images of the liver with quality comparable to a breath-held multi-echo Cartesian technique. Our new technique has potential for free-breathing characterization of liver fat content.
