Intermolecular multiple quantum coherences (iMQCs) possess some appealing unique properties for MRI. However, their intrinsic low signal to noise ratio prevents their widespread application. In this abstract, a new method was designed to produce a highly efficient localized distant dipolar field, thus substantially enhancing the iMQC signal intensity. Its application in MRI was tested. Experimental and simulation results indicate that the iMQC signal intensity is enhanced by more than two folds in comparison with the conventional CRAZED method.
