No major papers that directly compared the capability for N-stage evaluation among cDWIs with different b values, aDWI and FDG-PET/CT in NSCLC patients. We hypothesize that cDWI has a potential for improving diagnostic performance of N-stage in NSCLC patients as compared with aDWI as well as FDG-PET/CT, when set appropriate b value. The purpose of this study is to directly compare the capability for N-stage evaluation among cDWI with different b values, aDWI and FDG-PET/CT in NSCLC patients.
