Table 1.
Statistical analysis for the segmentation of the pulmonary trunk comparing manual observer and CAD measurements. Pearson correlation coefficients, absolute differences between measurements, and p-values of the paired t-tests are shown. Data were normally distributed.

| Intraobserver 2 | 0.88 | 2.11±1.53 | 0.05 |
| Interobserver | 0.92 | 1.53±1.4 | 0.2 |
| Observer 1-CAD | 0.93 | 1.48±1.09 | 0.1 |
| Observer 2-CAD | 0.88 | 2.17±1.49 | 0.05 |
| Inter-CAD user | 0.99 | 0.38±0.57 | 0.9 |
