Fig. 2

Visual representation of sampling strategy of the location and number of large 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 1L-ROI. The mean PDFF measured by yellow, red, and green ROIs on each single liver segment represents 3L-ROI. The mean PDFF measured by all yellow ROIs on all liver segments represents 9L-ROI. The mean PDFF measured by all yellow, red, and green ROIs on all liver segments represents 27L-ROI
