Table 5 Diagnostic performance of SUVmax, ADC, and SUVmax/ADC ratio for distinguishing TNM stages. Positive T stage was regarded as ≥T2b
Stage | SUVmax | ADC | SUVmax/ADC ratio |
|---|---|---|---|
AUC (95% CI) | AUC (95% CI) | AUC (95% CI) | |
T stage | 0.73 (0.52–0.95) | 0.64 (0.38–0.90) | 0.69 (0.44–0.93) |
N stage | 0.67 (0.39–0.94) | 0.69 (0.44–0.93) | 0.81 (0.57–1.00) |
M stage | 0.64 (0.37–0.90) | 0.75 (0.51–1.00) | 0.77 (0.56–0.97) |
