Table 4. Repeatability metrics for AI-generated PET.
Method | Metric | B (%) | stdev (%) | RC (%) | ICC |
---|---|---|---|---|---|
v1 | SUVmean | 13.15 | 22.02 | 61.04 | 0.895 |
SUVmax | 14.85 | 23.20 | 64.31 | 0.880 | |
v2 | SUVmean | 5.89 | 24.02 | 66.58 | 0.888 |
SUVmax | 6.33 | 26.84 | 74.40 | 0.880 |
Bias reported as mean relative difference from original AC-PET. Standard deviation (stdev), Repeatability Coefficient (RC), and Intraclass Correlation Coefficient (ICC) determined from mixed effects model accounting for clustered data.
