In this study, spin‐locking techniques were added as a part of intermolecular multiple‐quantum experiments, thereby introducing the concept of rotating‐frame intermolecular double‐quantum spin‐lattice relaxation, T 1ρ, DQC . A novel magnetic resonance imaging methodology based on intermolecular multiple‐quantum coherences is demonstrated on a 7.05‐T microimaging scanner. The results clearly reveal that the intermolecular double‐quantum coherence T 1ρ, DQC ‐weighted imaging technique provides an alternative contrast mechanism to conventional imaging.
