3 Tesla Magnetic Resonance Imaging (MRI)—Is it Ready for Prime Time Clinical Applications?
Magnetic resonance imaging (MRI) has advanced as one of the major tools for diagnostic imaging. The current benchmark in clinical imaging continues to be 1.5 T scanners. This review article examines if 3 T MRI is ready for prime time clinical applications. In the first part of the article, the history of clinical scanners will be discussed, including the 3 T development. The focus will then shift to the challenges and opportunities that 3 T's increased field strength brings. Special safety considerations and the technical requirements will be described, as well as a description of specific applications, along with the benefits and challenges at 3 T. The final sections will focus on a summary of optimization strategies and the importance of understanding the differences in imaging at 3 T.
