Abstract:

Intermolecular zero quantum coherences (iMQCs) have been applied to generate a new type of contrast shown to improve soft tissue characterization. However, the primary limiting factor for in vivo iZQCs signal intensity is relaxation. Two of the most significant contributions to relaxation are spin exchange and motional inhomogeneity. Both of these effects can be alleviated through spin locking, but the locking pulse sequence is dramatically different for iZQC sequence than for conventional sequences. We present our computer simulations of the related spin dynamics in order to optimize a zero-quantum (iZQC) spin locking sequence, and experimental verifications.
