An MR imaging method for quantifying fat fraction

There are two limitations with the Dixon method of quantifying fat fraction. The ambiguity over whether fat or water is the dominant species, and T1-weighting errors. We propose a method to resolve these limitations by using images taken over a range of TR values and using a least squares fitting method to obtain values for the fat fraction and the T1s. The method has been successfully modelled in a computer simulation incororating random noise into the MR signal.
