AbstractMagnetization transfer (MT) effect includes the interaction between bulk water and semisolid macromolecules (conventional MT) and the chemical exchange dependent saturation transfer (CEST) effect. MT asymmetry was investigated in human cervical spinal cord at 3T using low power off-resonance RF irradiation at different frequency offsets. Our results showed that the z-spectrum in gray/white matter was asymmetrical about the water resonance frequency (P < 0.001) with more saturation effect at lower frequencies (negative frequency offset) far from water and at higher frequencies (positive offset) close to water, which were attributed mainly to the conventional MT and CEST effects respectively.
