Kaplan–Meier analysis of 18F-FDG PET/MRI parameters for prediction of tumor treatment failure after head and neck cancer surgery. DFS and P values were as follows: a SUVmax (3-year DFS = 93.8 vs. 60.1%, P = 0.055), b MTV (3-year DFS = 79.8 vs. 40.4%, P = 0.004), c TLG (3-year DFS = 76.8 vs. 40.8%, P = 0.014), d ADCmean (3-year DFS = 93.8 vs. 57.3%, P = 0.024), e MTV/ADCmean (3-year DFS = 81.1 vs. 39.5%, P = 0.002), and f TLG/ADCmean (3-year DFS = 74.4 vs. 22.7%; P = 0.004)
