*Volume: tumor volume as determined from the CT scan, SUVmax: standard uptake value determined from the maximum voxel activity, RImax: retention index determined from the maximum voxel activity, SFmax: sensitivity factor determined from the maximum voxel activity, Kimax: kinetic index determined from the maximum voxel activity.
† P: assessed using the Wilcoxon test, NS: not significant.
