The non-contrast enhanced 4D MRA is time-consuming because of the needs to acquire high resolution data at multi-timepoints, which limited its clinical application.In current study, 4D-PACK combined with C-SENSE=6.5 can reduce 23% acquisition time(4 min 42s) for non-contrast enhanced 4D-MRA compared with 4D-PACK with SENSE acceleration, and the excellent acceleration advantage of C-SENSE can improve the clinical application for 4D MRA. the proposed acquisition scheme of 4DMRA with C-SENSE acceleration can be potentially used for evaluating arteriovenous malformation (AVM), arteriovenous fistulas (AVF), moyamoya disease, and stroke patients.
