Table A1.
Ablation study comparing dedicated models for T1 and T2 mapping images with a combined model. The table shows the mean and standard deviation of each metric over all samples.
| Model | Combined model | T1 only model | T2 only model | |
|---|---|---|---|---|
| Test sample type | T1 | T2 | T1 | T2 |
| IoU - Jaccard index () | 81.7 (9.07) | 78.39 (8.8) | 82.41 (8.16) | 82.73 (8.3) |
| Dice score () | 87.8 (8.79) | 85.02 (9.12) | 88.51 (7.51) | 88.78 (8.14) |
| Hausdorff distance (mm) | 3.97 (3.36) | 5.39 (7.69) | 3.79 (3.65) | 4.55 (9.41) |
| Mean surface distance (mm) | 1.77 (1.31) | 2.44 (5.52) | 1.77 (1.95) | 2.21 (6.11) |
