In vivo, the median and MLE ROI statistics of the lower SNR acquisitions return more accurate composite PDFF measurements than the mean when compared against the MRS PDFF values. Specifically, median and MLE statistics in the lower SNR PDFF maps (2D sequential CSE-MRI) made average estimation improvements over the mean of 1.7%, 1.1%, and 1.2%, respectively, when compared to MRS. As expected, mean, median, and MLE estimates show reduced bias in the higher SNR PDFF maps (3D CSE-MRI).
