↵* Metabolically active tumor volume as determined from [¹⁸F]FDG PET.
T_whole/p = whole tumor-to-plasma radioactivity ratio at 90–120 min or 160–180 min; T_max/p = maximum tumor-to-plasma radioactivity ratio at 90–120 min or 160–180 min; DV = distribution volume at 20–120 min or 160–180 min; ND = not detected.
