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.
