By
simultaneous acquisition of all echoes in one TR interval, T2* IDEAL is
superior to 3-pt IDEAL by allowing either larger spatial coverage or higher
resolution. Whether the fat content measured by the T2* IDEAL method is
influenced by the R2* effect of tissue or not is an important concern but
remains ambiguous. In this study, we verify the fat content measurements of
liver (lower R2* value) and vertebra (higher R2* value) in both methods
compared to the MRS method. Our results show no statistical difference of
liver and vertebral fat content in T2* IDEAL and 3-pt IDEAL methods.
