Effect of Noise and Estimator Type on Bias for Analysis of Liver Proton Density Fat Fraction
PURPOSE: Proton-density fat-fraction (PDFF) is typically measured from PDFF maps by calculating the mean PDFF value within a region of interest (ROI). However, the mean estimator has been shown to result in bias when signal-to-noise ratio (SNR) is low, resulting from a skewed distribution of PDFF no...
