【ねらいと概要（Aims & Scope）】
Commercially available preclinical imaging MRI systems cover a wide range of magnetic field strength from B0 <1 T up to 21 T. The very low-field systems may be used for educational purposes only. Systems with 1 T are able to produce most useful MR images of rats and mice. The pursuit of higher field strength is mainly driven by the desire to gain sensitivity allowing for shorter acquisition times and better spatial resolution. The obvious drawbacks of high field strengths are increased costs, limited RF penetration and more critical susceptibility effects. However, when considering small rodent applications (>95% of preclinical MRI scans are done with mice and rats) there is not much to be afraid of up to 11.7 T. High fields open the door to a wide range of applications like MR spectroscopy with a good chemical shift dispersion and much simpler J-coupling patterns, ultra-high spatial resolution down to 20 μm, heteronuclear MRI and MRS applications with, strong T2* contrast for e.g. BOLD fMRI. This presentation shall provide an overview of high-field animal MRI applications.
