Distant metastasis and/or recurrence are very important for management of patients with non-small cell lung cancer (NSCLC). We hypothesized that newly utilized Quick 3D and enhanced fat free (EFF) techniques could improve diagnostic performance of whole-body MRI at 3T system (whole-body 3T MRI) as compared with previously reported protocol, and might be at least as valuable as FDG-PET/CT in NSCLC patients. The purpose of this study was to directly and prospectively compare diagnostic capability for distant metastasis and/or recurrence assessment among whole-body 3T MRI with conventional protocol, that with Quick 3D and EFF and integrated FDG-PET/CT in NSCLC patients.
