Comparison of inter-hemispheric volumes correlations derived from each method
Left-right hippocampus | Left-right amygdala | |
---|---|---|
Manual segmentation | 0.85 | 0.75 |
FreeSurfer | 0.83 | 0.77 |
FSL-FIRST | 0.53 ** | 0.59 ** |
Pearson correlations of left against right hemispheric volumes obtained within a same segmentation method.
indicates a significant difference (at the p<0.0001 level) in the magnitude of the correlation, as compared with the correlation coefficients obtained with manual segmentation, as defined with the Fisher r-to-Z transform (ZPF) statistical test.
