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.
