AbstractDiffusion weighted (DW) images acquired with EPI sequence are prone to Nyquist ghost and geometric distortion. In this work, we applied a new phase labeling scheme we recently proposed to simultaneously correct both artifacts in DWI images. The artifacts in resultant phantom images are largely corrected, demonstrating that the proposed method can effectively remove both Nyquist ghost and geometric distortion in the DW-EPI images through a phase lebeling acquisition and post-processing.
