gyromagnetic ratioAn MRI term for a constant for a given nucleus which links the nuclear MR frequency to the strength of the external magnetic field, and corresponds to the ratio of the magnetic moment (field strength) to the angular momentum (frequency) of a particle. The value of the gyromagnetic ratio for hydrogen (1H) is 4,258 Hz/G or 42.58 MHz/Tesla.
