Recently, the introduction of 3 tesla (3T) magnetic resonance (MR) system for more sophisticated clinical applications has yielded in important benefits, especially in neuroradiology. The aim of this article is to illustrate the practical scientific applications of the 3T system in the neuroradiological filed. From the clinical point of view, we focused on the usefulness of 3T system for the diagnosis of several neurological disorders, such as brain tumors, vascular lesions, hemorrhagic lesions, acute cerebral infarcts and degenerative diseases. ⋯ This finding should not be mistaken for multiple system atrophy. 3T MR system indeed offers new potential because of a substantial increase in signal intensity provided by the higher magnetic field. Routine neuroradiologic imaging would benefit from higher magnetic field. However, It is required that extended knowledge of clinical data in comparison with 1.5T system to elucidate the efficacy of 3T system in the neuroradiology.
