23Na Triple Quantum (TQ) Signal Estimation from Single-Pulse Sequence with Single Quantum (SQ) Time Efficiency

This study demonstrates a method to estimate the biological relevant sodium TQ signal with a single-pulse sequence. Comparison of this method with theory and experiments using TQTPPI sequence showed a close agreement of the TQ signal. Therefore, the TQ signal can be estimated on the time scale of sodium SQ signal acquisition using the proposed sequence.
