Scatter plots and linear fitting curves of μRSK as a function of log10(HFF) for the 72 participants in group A. (A-I) Correspond to the average value of μRSK within the ROI of μRSK parametric images constructed using WSL =1, 2, 3, 4, 5, 6, 7, 8 and 9 PLs, respectively. The correlation coefficient, r, of log10(HFF) is 0.0938, 0.498, 0.592, 0.560, 0.579, 0.536, 0.534, 0.523 and 0.467 for WSL =1, 2, 3, 4, 5, 6, 7, 8 and 9 PLs, respectively. All the corresponding P values are <0.0001. HFF, hepatic fat fraction; ROI, region of interest; WSL, window side length; PL, pulse length.
