A single-point Dixon fat-water separation method is presented to address the concern of relative long scan times associated with multi-echo acquisition. The method derives field maps using the bias-corrected fuzzy C-means (BCFCM) algorithm from a single-echo data set. In vivo 3D experimental results demonstrate that the proposed technique offers robust fat-water separation from a single data set; the results are compared those generated by the three-point IDEAL technique.
