Our work aims at restoring undistorted DWI for breast imaging which is suffering from imperfect fat suppression and low SNR. We acquire two identical DWIs with reversed Phase Encoding Direction then apply correction in a manner of averaging magnetic field inhomogeneity. Corrected DWIs were compared with identical T2W NoFatSuppression images. Our methods well reconstruct the undistorted DWI,both location and signal intensity of lesion and breast are well maintained.
