In this study, we implemented a novel centric reordering scheme in a partial flow compensated 3D-iEPI to further reduce the flow effect and assessed its feasibility for a fast high-resolution SWI application. By properly dividing one interleave into two EPI shots sequentially acquired with opposite phase encoding gradient polarities and overlapping one line in the interleave center, we demonstrated that the partial flow compensated 3D-iEPI with such centric reordering scheme can significantly reduce the arterial contamination and obtain comparable contrast and image quality to 3D-GRE, whilst enjoying an approximate 2-fold reduction in acquisition time.
