Abstract
In a steady state free precession (SFP) magnetic resonance imaging method, after each pulse of an applied train of phase coherent RF pulses which excite magnetic resonance spins in a region of a body being examined, magnetic field gradients are applied to encode the excited spins and the encoded spins are detected, and at least one further magnetic field gradient is then applied to rephase the spins by the time the next RF pulse is applied.
