Purpose To rapidly obtain high resolution T2, T2*, and quantitative susceptibility mapping (QSM) source separation maps with whole‐brain coverage and high geometric fidelity. Methods We propose Blip Up‐Down Acquisition for Spin And Gradient Echo imaging (BUDA‐SAGE), an efficient EPI sequence for qua...
