To further increase SNR of 7T Phosphorus (³¹P) MRS in human brain, Nuclear Overhauser Effect (NOE) has been utilized where WALTZ waveform was often applied during relaxation time with low RF peak power and long pulse width with inherent narrow bandwidth. At higher field with larger chemical shift dispersion of the protons, broadband saturation of protons is desirable. This study demonstrated the feasibility of broadband NOE at 7 Tesla for ³¹P MRS of human brain.
