Dual-time-point FDG-PET for evaluation of lymph node metastasis in patients with non-small-cell lung cancer

Objective The objective of this study was to retrospectively evaluate whether delayed additional F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging can improve the certainty of this modality in evaluating lymph node metastasis in patients with non-small-cell lung cancer (NSCLC).
