No major reports have been reported the comparison of capability for differentiating recurrence from non-recurrence groups in candidates for surgical resection due to lung cancer among CEST imaging, DWI and PET/CT. We hypothesized that CEST imaging, which was determined as APT-weighted (APTw) imaging at 3.5 ppm, had equal or better potential for prediction of postoperative recurrence prediction in postoperative lung cancer patients, when compared with DWI and FDG-PET/CT. The purpose of this study was to compare the prediction capability of among single- and multi-parametric approaches by APTw imaging, DWI, and FDG-PET/CT in NSCLC patients.
