1. A method for measuring magnetization transfer (MT) of magnetic resonance (MR) signals, the method comprising:
providing a first MT sequence and a second MT sequence, each comprising a radiofrequency (RF) saturation block, wherein:
the first MT sequence comprises a predetermined first RF saturation power and a predetermined first RF saturation frequency offset from water,
the second MT sequence comprises a second RF saturation power and a second RF saturation frequency offset from water,
the second RF saturation power is greater than the first RF saturation power by a factor c, and
the second RF saturation frequency offset is greater than the first saturation frequency offset by the factor c;
acquiring a first MR signal and a second MR signal using the first MT sequence and the second MT sequence; and
measuring the MT via a difference between the first MR signal and the second MR signal.
