Ultra-high field strengths provide higher signal to noise ratio and improved separation of metabolites in spectroscopy, allowing for more precise characterization of peaks. In particular, this improved peak resolution may be of benefit for characterization of the downfield (5-10ppm) spectrum, which is not yet well characterized; this experiment aims to improve knowledge of downfield peaks by investigating their exchange rates and T1 values at 9.4T, using inversion transfer experiments and metabolite cycling to allow for non-water suppressed acquisition.
