No direct comparisons of therapeutic effect prediction have been performed among dynamic perfusion ADCT, dynamic perfusion MRI and FDG-PET/CT in small cell lung cancer (SLCLC) patients. We hypothesize that multiparametric approach by dynamic CE-perfusion ADCT, MRI and FDG-PET/CT can improve therapeutic effect prediction capability in SCLC patients, when compared with each modality assessment. The purpose of this study was to directly compare the capability for therapeutic outcome prediction among dynamics CE-perfusion ADCT and CE-perfusion MRI assessed by same mathematical method and FDG-PET/CT in SCLC patients assessed as limited disease (LD).
