(a) Photograph of three water-fat phantoms that were constructed using different concentrations of distilled water and Intralipid. One milligram of manganese chloride was dissolved in each phantom to create a T2* shortening effect. The expected fat fraction value is shown for each phantom. The remaining phantoms in the photograph were not a part of this experiment. (b) The estimated fat fractions using IDEAL without T2* compensation. An overestimation of between 4-5% is seen when T2* is not accounted for. (c) The estimated fat fractions using IDEAL with T2* compensation (T2*-IDEAL). The estimated values agree closely with the expected values. (d) The estimated fat fractions using the proposed method at 3.4x acceleration. Accurate estimates are maintained at this acceleration factor. In addition, a similar image quality is observed between the proposed method and T2*-IDEAL.
