Pearson correlation coefficient R and Bland–Altman analysis for liver fat measurements (PDFF, PDFF_MRS, FF_T1).
| R | Mean Bias | 95% CI | |
|---|---|---|---|
| PDFF_MRS vs. PDFF FF_T1 vs. PDFF FF_T1 vs. PDFF_MRS |
0.954 | 0.57 | −3.29, 4.43 |
| 0.930 | 0.78 | −3.27, 4.82 | |
| 0.922 | 0.21 | −4.30, 4.71 |
PDFF: proton density fat fraction (from MR imaging); PDFF_MRS: proton density fat fraction (from MR spectroscopy); FF_T1: fat fraction, calculated from T1 mapping combined with a 2-point Dixon method; CI: confidence interval.
