Range of R2* values and mean ± SD R2* values across patients (74/39 available data sets at 1.5 T/3 T) for the employed imaging protocols and the 3 different fitting approaches.

Note: Mean R2* values were compared for each fitting algorithm and each field strength by the Wilcoxon signed rank test. Significant differences in the comparison of non-FS and FS as well as non-FS and corrected FS values are indicated by the § symbol. Abbreviations: min., minimum; max., maximum; SD, standard deviation; non-FS, without fat saturation; FS, with fat saturation; corr. FS, corrected fat saturation.
