Figure 5.
ROC curves for CT, PET/CT, MRI, C-M, C-P, M-P, C-M-P in lymph node assessment. Comparisons of AUCs between the groups of separate examination showed that the AUC of PET/CT was significantly superior to that of CT but there was no significant difference to MRI (p = 0.0172, p = 0.0846, respectively) (a). There was no significant difference of AUC between combined examination groups (p > 0.05) (b). AUC did not show more obvious superiority in lymph node assessment when CT was compared with C-P and when MRI was compared with M-P, respectively; (p > 0.05) (c,d).
