The VAT technique has been applied in ss-EPI to eliminate the distortion along the phase encoding direction. However the long echo spacing in ss-EPI will lead to more phase errors introduced by B0 inhomogeneity and require more VAT gradient, which results an increasing image blurring and limits the spatial resolution. The rs-EPI features much shorter echo spacing compared with ss-EPI, which could be much suitable for VAT. In this study, the VAT technique is integrated into a rs-EPI sequence to further improve the distortion. In addition, phase modulated pulse is used to reduce the image blurring caused by VAT.
