Receiver operating characteristic curve analysis of I-PET-derived parameters to predict disease progression (a); areas under the curve were 0.811 for ΔSUVmax_(LLR) (p < 0.0001), 0.788 for ΔSUVmax_(LMR) (p < 0.0001) and 0.781 for ΔSUVmax (p < 0.0001), respectively. Receiver operating characteristic curve analysis of I-PET-derived parameters to predict disease death (b); areas under the curve were 0.748 for ΔSUVmax_(LLR) (p = 0.0005), 0.738 for ΔSUVmax_(LMR) (p = 0.0005) and 0.730 for ΔSUVmax (p = 0.0011), respectively
