This work investigates potential sources responsible for MR signal delay we observed and reported before. Computer simulations and phantom studies showed that mobile ions (electrically-charged particles) may be the source for MR signal delay, rather than imperfect performance of the MRI system such as gradient dephasing, B0-field inhomogeneity or chemical shift.
