Three-dimensional intermolecular multiple-quantum coherence sequences are proposed to achieve high-resolution 2D MRS such as COSY and J-resolved spectroscopy under inhomogeneous fields. Delay acquisition and foldover correction schemes are utilized to reduce the scanning time of the 3D spectrum. Primary measurements are performed on phantoms under inhomogeneous fields to test the feasibility of the proposed sequences.
