Consistency and prognostic value of preoperative staging and postoperative pathological staging using 18 F-FDG PET/MRI in patients with non-small cell lung cancer.

In NSCLC, pathologic staging was better at predicting recurrence, and preoperative PET/MRI staging was better at predicting survival. Preoperative staging by PET/MRI was superior to CT in diagnosing hilar and mediastinal lymph-node metastases, which contributed to the high concordance with pathologic staging.
