WebNo apparent fat-water swap was observed in the low SNR (SNR ~ 10) dataset. Accurate proton density fat fraction results were also produced from the proposed method. Conclusion. A method based on fat-water transition region extraction was proposed for robust water-fat separation and fat fraction quantification. WebThe possible reason might be that Dixon fat separation techniques avoid the potentially severe suppression artifacts due to B 0 inhomogeneities and frequency offsets among separate volumes of interest, including inadvertent suppression of the water signal, which can reduce image contrast[19,20]. This results also might be in part affected by ...
