Images obtained by inhomogeneous magnetization transfer were analyzed using models involving Zeeman and dipolar orders. These orders are affected by spin diffusion and relaxation. In the current study a method that enables the measurement of these processes in spinal cord by the same pulse sequence is presented. Magnetization transfer time (MT, spin diffusion) between CH2 groups is ~0.1ms while the MT between them and CH3 groups is much slower (~2ms). The dipolar order is found to decay by three exponentials process (0.11, 0.86, 11.4ms). The fastest decaying component is compatible with the spin diffusion between the CH2.
