Accurate quantification of the liver fat content is an important factor in detecting hepatic diseases. A multi-echo approach can be used effectively for liver fat quantification. However, the presence of macroscopic field inhomogeneities shortens T2* values and can lead to underestimated T2* values of fat content in liver. This study propose correcting method for these macroscopic inhomogeneities to accurately quantify T2* values and fat, water content using multi-echo 2D liver imaging.
