Simultaneous Time-of-Flight (TOF) MR Angiography, SWI and QSM without compromising TOF features

Abstract

Multiple-echo gradient echo sequences developed to simultaneously compute TOF-MRA, SWI and QSM in previous studies have either compromised TOF-MRA features or have not computed QSM. In this abstract, images were acquired in healthy volunteers at 3T with different parameter variations of the proposed 3D triple-echo gradient echo sequence with all TOF-MRA features. The effect of TOF-MRA features on phase and QSM were explored and corrected to obtain artifact-free QSM. The parameters of the sequence have been optimized to obtain TOF-MRA, SWI, QSM and R2* maps simultaneously.
