T1WI can be used to measure liver volume and observe fat distribution; IP-OP method gives a FC that is significantly lower than the actual value, especially in higher fat concentrations; CSI and 1H MRS are accurate in quantifying fat in both phantoms and liver in vivo. Given their excellent correlation and concordance with LL analysis, CSI and MRS may replace liver fat histological and chemical analysis in longitudinal studies.
