We hypothesize that CEST imaging has a potential for therapeutic effect prediction in NSCLC patients treated with chemoradiotherapy and may be at least as valuable as DWI and FDG-PET/CT. Moreover, combined predictors may improve therapeutic effect prediction capability, when compared with single predictor from MRI or PET/CT. The purpose of this study was to compare the capability of therapeutic effect prediction for chemoradiotherapy among CEST imaging, DWI, FDG-PET/CT and combined predictors from MRI and PET/CT in NSCLC patients.
