3.0 T magnetic resonance in neuroradiology

Ever since the introduction of magnetic resonance (MR), imaging with 1.5 T has been considered the gold standard for the study of all body areas. Until not long ago, higher-field MR equipment was exclusively employed for research, not for clinical use. More recently, the introduction of 3.0 T MR machines for new and more sophisticated clinical applications has yielded in important benefits, especially in neuroradiology. Indeed, their high gradient power and field intensity allow adjunctive and more advanced diagnostic methodologies to be applied with excellent resolution in a fraction of the time of acquisition compared with earlier machines. The numerous advantages of these machines in terms of higher signal, increased spatial resolution and greater sensitivity, and their few limitations, which can be overcome and anyway do not adversely affect diagnostic efficacy, will make 3.0 T MR systems the gold standard for morphological and functional studies of the brain.
