FCH-PET/MRI could therefore be the ideal examination for the initial staging of HCC, combining in a single multimodality investigation the reference morphological imaging technique and an efficient functional one. The hypothesis of this study is that FCH-PET/MRI is able to detect, in patients eligible for curative treatment, additional preoperative intra- and extra-hepatic early or metastatic HCC unseen or equivocal with conventional imaging (CT and MRI) and responsible for recurrence or disease progression at 6 months.
