Predicting the rupture of Aortic Aneurysms is a complex problem that interests, from several decades, many researchers. The works on this issue are very complex, involving both the study of mechanical behavior of the artery as the flow of blood. The Magnetic Resonance Imaging (MRI) technique allows to obtain anatomic information of the arteries, than the flow inside thereof. The goal of this study is an inter comparison between flow data from MRI and those obtained by Particle Image Velocimetry (PIV). An experimental device simulating hemodynamic circulation is used. Initially in order to validate the device, the flow in a cylindrical glass tube is measured by these two techniques and then compared to a theoretical model. Secondly, the flow in a phantom in silicone, with an axisymmetric aneurysm, is evaluated with 4D flow MRI sequences and the easurements are compared with those obtained by PIV with good agreement. The ability of the MRI technique to measure the flow thus makes an essential device for the study of cardiovascular disease
