Triple
quantum (TQ) sodium imaging is an effective means decreasing the contribution
from the intracellular and fluid spaces to the sodium (23Na) signal. The
sodium TQ signal is, however, much weaker than the single quantum (SQ, or
total tissue) signal (~1/10). In this study, we evaluate the SNR performance
of TQ sodium MRI of the human brain at both 7T and 3T. Our results
demonstrate that the theoretical SNR gains of 7T have tremendous benefits for
TQ sodium MRI.
