No one reported direct comparisons for TNM staging capability among whole-body MRI and PET/MRI at 1.5T and 3T systems and PET/CT in NSCLC patients. We hypothesize that whole-body MRI and PET/MRI at 1.5T and 3T MR systems have better potential for TNM stage assessment than whole-body FDG-PET/CT in NSCLC patients. The purpose of this study was to prospectively and directly compare TNM stage classification capability among whole-body MRI and PET/MRI at 1.5 and 3T MR systems and PET/CT in NSCLC patients.
