(A) Sampling masks of the standard-EPI with 5/8 phase-encoding partial Fourier and circular-EPI with both readout and phase-encoding partial Fourier. (B) Reconstruction performance comparison of BUDA-EPI vs. synthesized BUDA-circular-EPI with additional RO-pF generated from the same dataset. BUDA-circular-EPI reconstructed using SENSE without S-LORAKS resulted in missing high k-space data (reconstructed k-space of one of the two blip-up&down EPI-shots is shown), while incorporating S-LORAKS into the reconstruction can help effectively recover the missing k-space data. (C) reconstructed results and the difference maps of reference BUDA-standard-EPI (both magnitude and phase images of blip-up &down EPI-shots are shown), BUDA-circular-EPI with SENSE and S-LORAKS for b= 1000 s/mm2 images.
