No one has compared the capability among DWIs obtained by EPI and FASE at a 3T MR system and PET/CT for prediction of postoperative clinical outcome. We hypothesize that DWI obtained by FASE sequence are more useful than that by EPI sequence at 3T MR system and PET/CT for predicting postoperative recurrence and treatment outcome in NSCLC patients with surgical treatment. The purpose of this study was to directly and prospectively compare the quantitative capability for prediction of postoperative recurrence and treatment outcome among DWI with FASE and EPI sequences at 3T system and FDG-PET/CT in NSCLC patients.
