Results of Analyses of Spatial Alignment for Both Patient Groups
| Parameter | Standard CT and PET | Triggered CT and PET | P |
| Mismatch of lung–liver boundary (mm) | 9.2 ± 8.1 | 4.5 ± 6.7 | <0.001* |
| Average distance between lesion centroids (mm) | 6.3 ± 4.0 | 5.6 ± 4.2 | 0.424 |
| Jaccard similarity coefficient | 0.30 ± 0.21 | 0.32 ± 0.20 | 0.609 |
| SUVmax (g/cm3) | 10.5 ± 6.7 | 10.9 ± 6.7 | <0.001* |
| SUVmean (g/cm3) | 6.1 ± 4.0 | 6.4 ± 4.0 | 0.001* |
↵* Significant difference between 2 groups.
Numbers are averages and SD for all patients (i.e., scanned on Biograph 40 mCT and on Biograph 64 mCT Flow scanner).
