MTR, or magnetization transfer ratio, delivers an extra pulse of energy to the protons that are bound to myelin and then measures how much of that energy is transferred to the free water nearby.

Through magnetization transfer ratio (MTR), developed about five years ago, doctors can see how severe the tissue damage is from MS--damage that can go undetected by traditional MRI.
(31) By utilizing a special off-resonance pulse, magnetization transfer (MT) reduces signal intensity in normal white matter, resulting in enhanced contrast and detection of lesions; an additive contrast effect can be obtained with gadolinium-enhanced images.
