Clinical stage assessment is important for treatment in NSCLC patients. We hypothesized that whole-body MRI at 3T MR system, which is utilized multiple array coil with parallel imaging capability and Quick 3D sequence with DFS technique, has equal to or better potential for T, N and M factors and operability assessments in NSCLC patients than co-registered FDG-PET/MRI and integrated FDG-PET/CT. The purpose of this study was to directly compare the capability for clinical stage and operability assessments among whole-body MRI, co-registered FDG-PET/MRI and integrated FDG-PET/CT in NSCLC patients.
