摘要
Magnetic resonance (MR) imaging at 3 T is clinically feasible and, in the right context, can provide improvements compared with 1.5-T MR imaging. Improvements in both signal/noise ratio and contrast/noise ratio can be used to improve image homogeneity and/or spatial and temporal resolution. Some techniques, such as brain functional MR imaging, are considered far superior at 3 T than at 1.5 T. Although several challenges still exist, 3 T has been become well established in clinical MR imaging.
