Metrics with p < 0.05 were considered to be significant but all of the metabolic parameters have much smaller P values. The number of subjects with anatomic imaging data at the each of the time points was 29, 25, 25 and 27, while the number of subjects with metabolic imaging data was 28, 24, 21 and 26. There were 4 subjects censored for PFS and 10 subjects censored for OS
