Recurrence assessment is very important for management of postoperative non-small cell lung cancer (NSCLC) patients. We hypothesized that whole-body PET/MRI and MRI with DWI have a potential for improving recurrence assessment as compared with whole-body PET/CT and conventional radiological examinations in NSCLC patients. The purpose of this study was to directly compare the diagnostic performance for postoperative lung cancer recurrence assessment among whole-body PET/MRI, MRI with and without DWI, PET/CT and conventional radiological examination in NSCLC patients.
