Abstract:
A magnetic resonance imaging method which facilitates a pre-compensating phase encoding of spuriously generated magnetizations, wherein the method comprises generating a pulse sequence which may be represented as being disposed upon an RF-excitation line, a phase-encoding axis, a slice-encoding axis and a frequency-encoding axis, said method further comprising the steps of:generating a preparatory excitation of spins represented upon the RF-excitation line, applying subsequently a temporary magnetic compensation gradient as represented along the phase-encoding axis, generating subsequently an RF excitation pulse as represented upon the RF-excitation line, applying subsequent to said RF excitation pulse, and before an acquisition interval for receiving magnetic resonance signals, a phase-encoding gradient as represented along the phase-encoding axis, which phase-encoding gradient is substantially the same magnitude as, and opposite in direction relative to the direction of said temporary magnetic compensation gradient, and receiving magnetic resonance signals during said acquisition interval as represented along the RF-excitation line.
