The ability to perform phase correction during PROPELLER-EPI image reconstruction is highly advantageous making PROPELLER-EPI a robust segmentation scheme for fast high resolution echo planar imaging. However, only modified phase information is obtained after the complete image reconstruction, hampering further processing of the image phase. To avoid this issue and to make SWI processing of PROPELLER-EPI data possible we propose to perform the processing of phase information on the blade level, before image phase is modified in any way. We show that this reconstruction scheme enables high resolution susceptibility weighted imaging using a fast EPI readout.
