Three-point Dixon method with a MISSTEC sequence.
We propose an adaptation of the MISSTEC sequence (simultaneous acquisition of a spin echo and several stimulated echoes) for performing fat suppression with a three-point Dixon method. In vivo measurements were performed on healthy volunteers using a sequence of three echoes (one spin echo and two stimulated echoes) within a third of the acquisition time taken by the regular three-point method, with the same spatial resolution and with half the signal-to-noise ratio (SNR). Homogeneity of fat suppression was greatly increased in comparison with the two-point method.
