Table 1. Comparison between the topological properties of the human brain anatomical networks derived from the conventional DTI and FLAIR-DTI datasets.
Global parameters | Conventional DTI (Mean ± SD) | FLAIR-DTI (Mean ± SD) | t-value | p-value |
Eglob | 0.679±0.063 | 0.737±0.062 | −2.634 | 0.016* |
Eloc | 0.986±0.076 | 1.064±0.082 | −2.354 | 0.029* |
Cw | 0.339±0.018 | 0.352±0.019 | −1.535 | 0.140 |
Lw | 1.486±0.151 | 1.366±0.107 | 2.510 | 0.021* |
S | 0.145±0.014 | 0.159±0.013 | −2.255 | 0.036* |
The negative (positive) t-value indicates that the value of the global parameter corresponding to the FLAIR-DTI datasets is higher (lower) than that of the conventional DTI datasets. The symbol (*) stands for statistically significant difference, as determined by a threshold of p<0.05.
