Hepatocellular carcinoma (HCC) is the fifth most common cancer in terms of incidence and the second in terms of mortality. At an early stage, which is based on a low number and size of liver nodules and the absence of extra-hepatic locations (Milan criteria), a curative treatment can be performed, i.e. liver transplantation, surgical resection, or thermo-ablation. These treatments can lead to severe complications, so patients benefiting from them must be carefully selected. The correct identification of all HCC lesions at the time of the therapeutic decision is crucial. MRI is the reference examination for diagnosis but its field of exploration is limited to the upper abdominal area and its sensitivity decreases for nodules of less than two centimetres. Such lesions could actually be HCC that will cause early post-operative progression.
