Recently, a distortion- and blurring-free acquisition method called PSF-EPI has been used in DWI. However, when field inhomogeneity is severe, DW images may become noisy and more shots are needed to get the reliable results. In this work, we introduce a low-rank based reconstruction method using signal correlation along the ky-encoding dimension in PSF-EPI to improve image quality and reduce needed shot number to shorten scan time. High-resolution in-vivo data were used to test the performance of the proposed method. The results show that the quality of the images is improved.
