METHOD FOR REDUCING ARTIFICIAL EFFECT OF MR IMAGE GENERATED FROM ATOMIC NUCLEUS FLOWING BY ADJUSTING GRADIENT MOMENT TO ZERO

摘要

A technique has been developed which reduces blood-flow artifacts in multi-echo, multi-slice magnetic resonance (MR) imaging by rephasing spins which have arbitrary velocity as well as static spins. The technique requires tailoring of the gradient structure along at least one of the three axes so as to null out in the preferred embodiment the zeroth and first moments of the gradient distributions.
