Multi-contrast images including hemodynamic information in one sequence have significant impact in evaluating intracranial vessels. In this work, we proposed to use FOCI inversion pulse combined with the multi-contrast sequence iSNAP to further improve image quality of dynamic and static MRA. Promising results were obtained from both phantom and in vivo data.
