GMC analysis for VBM models at 12 mm and a T-threshold of 3.7a
| Model | Concordant Rate (%) | Specificity (%) | Discordant Rate (%) | Euclidean Distance (Range, 0–141.14) | Concordant Rate/Discordant Rate |
|---|---|---|---|---|---|
| T1 | 38.5 | 33.9 | 84.6 | 90.29 | 0.46 |
| T1+T2 | 46.2 | 40.3 | 53.8 | 80.37 | 0.86 |
| T1+FLAIR | 46.2 | 37.1 | 61.5 | 82.77 | 0.75 |
| T1+T2+FLAIR | 46.2 | 35.5 | 76.9 | 84.00 | 0.60 |
↵a For VBM GMC 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 3.7, respectively.
