There are no major papers that compared differentiating capability of SPNs among actual DWI (aDWI), computed DWIs (cDWIs)with different b values and FDG-PET/CT in patients with SPN. We hypothesize that cDWI obtained appropriate b value can improve the capability for differentiating malignant from benign SPNs as compared with aDWI and FDG-PET/CT. The purpose of this study is to directly compare the capability for differentiating malignant from benign pulmonary nodules among aDWI, cDWIs with different b values and FDG-PET/CT.
