Table 3. Correlation of whole-liver segmentation and the ROI sampling method.
Hepatic steatosis severity | HFF of whole-liver segmentation (%) | HFF of ROI sampling method (%) | r | P value |
---|---|---|---|---|
Healthy (n=223) | 3.10 (2.50, 3.90) | 2.56 (2.01, 3.28) | 0.943 | <0.001 |
Mild (n=97) | 7.80 (6.30, 10.00) | 7.71 (6.25, 10.00) | 0.990 | <0.001 |
Moderate (n=29) | 17.00 (14.30, 22.37) | 18.03 (15.15, 22.37) | 0.961 | <0.001 |
ROI, region of interest; HFF, hepatic fat fraction.
