520 |a The rapid developments in magnetic resonance imaging (MRI) over the past 20 years have affirmed its supremacy over most other means of non-invasive exploration of the human body. This progress has had other consequences for imaging physicists: having knowledge about only one of the sides of MRI is nowadays no longer enough to develop new sequences or even to learn more about those that already exist. It is necessary to have a clear and precise view of all the fields explored today by this imaging technique, such as rapid imaging, flows, diffusion, perfusion or even functional MRI. This bo.
