FIGURE 1.
Bland–Altman plots of difference in SUVmax vs. average SUVmax: 10 patients (51 lesions) with repeat scans using same scanner (A); 2 patients (34 lesions) using different scanners from same academic institution (B); and 11 patients (77 lesions) using different scanners from different sites (C). Within each panel, plotting character/color is same for multiple lesions in single patient. Dashed lines = average difference and 95% limits of agreement. The 2 lesions from melanoma patient (SUVmax, 38.3 and 25.0 on first scan and 19.2 and 16.4 on second scan) are not shown in C but contribute to limits-of-agreement calculations.
