Benefits, Challenges and Applications of Ultra-High Field Magnetic Resonance

• Human ultra-high field (UHF) MR at 7T and above has been on a rapid rise since the first installations in the 1990s, motivated by the opportunities created by SNR gains and contrast changes. Research efforts were for long focused mainly on technological developments to cope with the challenges posed by UHF. This has brought 7T MR neuroimaging to maturity and into an application dominated realm, further accelerated by the availability of clinically certified commercial 7T systems. This chapter aims to give an overview of UHF MR in a neuroimaging context by first providing an overview of the basic physical motivations for going to higher fields. It will then describe the challenges and limitations of working at higher field strengths, and outline some of the currently available solutions. This chapter also provides a discussion of the potentials of UHF by highlighting some of the neuro applications that benefit from UHF.
