Contribution of Phase-Contrast Magnetic Resonance Imaging in the study of hepatic fibrosis: preliminary results

INTRODUCTION Hepatic fibrosis is secondary to many etiologies (alcohol, viruses...) and the quantification of this fibrosis is a key point for the clinician. Hepatic puncture biopsy is the invasive gold standard for the assessment of degree of fibrosis. Many techniques, more or less reliable and a bit or not invasive, have been developed to evaluate it. Among those techniques, utrasonic transient elastography is widespread owing to the simplicity of the examination. During hepatic MRI exploration, morphological images are usually collected but we can also reach functional data using Phase contrast sequences (PC-MRI) . In this work, we wanted to appraise the potential links between elastometry data and parameters measured by PC–MRI.
