Magnetic resonance angiography by selective inversion recovery using a compact gradient echo sequence.
We have studied a pulse sequence using compact imaging gradients for MR angiography by selective inversion recovery. By acquiring signals approaching a half-echo, we achieve significant immunity to artifacts from flow-induced dephasing. Initial clinical results on carotid arteries accurately depict stenoses without the problems of signal dephasing.
