Basic concepts of Magnetic Resonance Imaging

Fundamental aspects of the Magnetic Resonance Imaging (MRI) technique which is one of the preferred modalities for non-invasive clinical applications and "in vivo" medical and biological research, are presented. The physical principles of MRI and protocols recently introduced to investigate the microscopic details of pathological cerebral damages are introduced. The main results obtained from the analysis of T2 relaxation curves are briefly summarized.
