Fig. 1

Visual representation of sampling strategy of the location and number of regions-of-interest (ROIs) placed by the readers on proton density fat fraction (PDFF) maps. Yellow, red, and green circles represent the first, second, and third ROIs placed in each liver segment, respectively. The PDFF measured by yellow ROIs on each single liver segment represents 1S-ROI. The mean PDFF measured by yellow, red, and green ROIs on each single liver segment represents 3S-ROI. The mean PDFF measured by all yellow ROIs on all liver segments represents 9S-ROI. The mean PDFF measured by all yellow, red, and green ROIs on all liver segments represents 27S-ROI
