Abstract

In the last decade, magnetic resonance imaging (MRI) has played the main role in the study of diseases affect­ing the central nervous system (CNS). The main limita­tions of the first commercial units were predominantly represented by long acquisition times and low spatial resolution. The dramatic technological developments of the 1990’s have made it possible to overcome these lim­itations by selectively enhancing each parameter influ­encing the magnetic resonance (MR) signal, and have paved the way to functional studies with medium field units.
