Spatial resolution in 31P metabolite imaging of the human brain at 4.1 T.
In studies of 31P metabolite imaging in the human brain using a high-field 4.1 T NMR system, resolution and signal-to-noise ratios were measured to determine the potential for spatial-resolution improvements. The results suggest that spatial resolution of FWHM of 2 cm or less, similar to that of radionuclide tomographic functional images, may be feasible.
