Some of this deposited energy is then transferred to the free water pool primarily via dipole-dipole interactions. Depending on the degree of coupling between the pools, the free water pool becomes partially saturated. If the free water pool is subsequently imaged using routine RF pulses and gradients, its signal will be reduced secondary to an MT effect. I personally find it helpful to think of MT pulses as "macromolecule sat pulses" which selectively suppress tissues with significant water-macromolecule interactions.

All the major vendors use the generic terms magnetization transfer, MT, or MTC to refer to this technique. Toshiba, however, uses a much longer but more descriptive trade name, SORS-STC, which stands for "Slice-Selective Off-Resonance Sinc Pulse Saturation Transfer Contrast".
