As a new method for contrast enhancement in MRI, the intermolecular multiple quantum coherences (iMQCs) MR imaging has recently attracted considerable attention mostly because of the intrinsic sensitivity of the iMQCs to changes the magnetization and susceptibility structures. Relaxation times (T1 and T2) play an important role in creating and determining susceptibility structures of the matters for MRI detection. In this study, we have experimentally and numerically investigated the relaxation time dependence on the intensity profiles and/or contrasts of the intermolecular double quantum coherences (iDQCs) MR images by fixing and varying T1 and T2, respectively and vice versa.
