Abstract

Functional 31P spectroscopy has been investigated in several studies with greatly varying results, which may be due to the low sensitivity of the 31P nucleus. We have taken advantage of the high SNR at 9.4 T to acquire spectra from the human visual cortex under stimulation. Experiments were performed with different localization volumes, defined by saturation pulses. In spite of the excellent quality of the obtained data, no stimulation-related changes in metabolite concentrations or resonance frequencies could be detected.
