GMV analysis for VBM models at 12 mm and a T-threshold of 3.0a
| Model | Concordant Rate (%) | Specificity (%) | Discordant Rate (%) | Euclidean Distance (Range, 0–141.14) | Concordant Rate/Discordant Rate |
|---|---|---|---|---|---|
| T1 | 23.1 | 21.0 | 84.6 | 110.25 | 0.27 |
| T1+T2 | 7.7 | 17.7 | 76.9 | 123.66 | 0.10 |
| T1+FLAIR | 38.5 | 9.7 | 84.6 | 109.25 | 0.46 |
| T1+T2+FLAIR | 38.5 | 14.5 | 76.9 | 105.32 | 0.50 |
↵a For VBM GMV automated analysis (prior to visual interpretation), values of concordant rate, specificity, discordant rate, Euclidean distance from CR = SP = 100, and concordant/discordant ratio are provided for all models: namely, T1, T1+T2, T1+FLAIR, and T1+T2+FLAIR. The smoothing level and T-threshold are 12 mm and 3.0, respectively.
