An initial study on the comparison of diagnostic performance of F-FDG PET/MR and F-FDG PET/CT for thoracic staging of non-small cell lung cancer: Focus on pleural invasion.

Objective: To compare the diagnostic performance of F-FDG PET/MR and PET/CT preliminarily for the thoracic staging of non-small cell lung cancer (NSCLC) with a special focus on pleural invasion evaluation.

Methods: 52 patients with pathologically confirmed NSCLC were included and followed for another year. Whole-body F-FDG PET/CT and subsequent thoracic PET/MR were performed for initial thoracic staging.
