- Group 2 will be constituted of 60 patients with resectable HCC eligible for surgery. This group will enable to evaluate the tumoral environment invasion. Patients of this group will be selected during multidisciplinary medical meetings. If they accept to participate to the ancillary study, a blood sample will be collected (2 tubes of 6 mL and 10 mL respectively) just before the MRI, an exam always performed before hepatic resection with a 5-minute- additional sequence to measure FRM. As soon as the surgery is performed, surgery pieces will be analysed by anatomopathology laboratory in order to assess, notably, presence of mirco-vascular invasion.
