Whole-body MRI has the capability for cancer screening and/ or staging similar to FDG-PET. However, no direct comparisons about diagnostic accuracy of M-stage in lung cancer were reported. The purpose of the present study was to prospectively compare diagnostic accuracy of M-stage between whole-body MRI and PET in lung cancer patients. 70 lung cancer patients underwent whole-body MRI and PET, and compared their diagnostic capabilities on per patient basis. There were no significant difference of diagnostic capability between two methods (p>0.05). In conclusion, whole-body MRI can accurately diagnose M-stage in lung cancer patients, similar to PET.
