High order eddy currents (HOEC) can cause significant, direction-dependent image distortions and image shape/intensity discontinuities between station boundaries in whole body diffusion weighted imaging (WB-DWI). In this paper, we use a combined prospective and retrospective compensation method to correct HOEC induced distortions. WB-DWI volunteer results show that the method can effectively reduce in-plane distortion, misregistration, and station boundary discontinuities, thus significantly improving WB-DWI image quality.
