Advances in clinical 3-tesla neuroimaging.

Three-tesla magnetic resonance (MR) imaging represents one of the major forefronts of diagnostic neuroradiology today. Heat deposition, changes in T1 relaxation rates, susceptibility differences, and greater inherent sensitivity to motion artifacts represent challenges to clinical implementation. However, the situation appears remarkably similar to that encountered almost 15 years ago as the field of MR transitioned from 0.
