Hepatic fibrosis is secondary to many etiologies and quantification of this fibrosis is a key point for the clinician. In this work, we wanted to appraise the potential links between elastometry data and parameters measured using PC-MRI in 17 subjects developing hepatic pathologies. Three distinct groups, probably representative of the stage of hepatic fibrosis, clearly appear A statistically significant linear correlation between the elasticity modulus and the vessel area variations DS or the portal congestion index IC is clearly highlighted. PC-MRI could be a useful and complementary tool for the understanding of evolution mechanisms involved in hepatic fibrosis.
