Bland–Altman plots of SUV metrics for all lesion-level ROIs (411 lesions): SUVmax (A), SUVmean (B), and SUVtotal (C). Different sites are indicated by different symbols (▪ = UWCCC, ● = MSKCC, and ▲ = NCI). Solid line denotes mean difference, and dotted lines denote upper and lower 95% LOA. Both mean and difference uptake values have been log-transformed.
