Dice score between the original nnU-Net and the proposed framework.
| LV | RV | LA | RA | MPA | LPA | RPA | AA | |
|---|---|---|---|---|---|---|---|---|
| nnU-Net | 82.4 ± 7.8 | 86.9 ± 6.8 | 86.9 ± 5.2 | 88.9 ± 10.3 | 91.6 ± 5.5 | 90.8 ± 2.9 | 86.4 ± 5.1 | 84.5 ± 9.0 |
| Proposed framework | 83.2 ± 7.1 | 87.0 ± 7.0 | 87.4 ± 4.7 | 90.7 ± 5.8 | 92.5 ± 3.4 | 91.3 ± 2.4 | 86.9 ± 4.6 | 86.4 ± 8.0 |
Note. The values show the mean (±standard deviation) of all images from the CTPA for each segmentation label. AA, ascending aorta; LA, left atrium; LPA, left pulmonary artery; LV, left ventricle; MPA, main pulmonary artery; RPA, right pulmonary artery; RA, right atrium; RV, right ventricle.
