VAT-DIADEM is able to accelerate the distortion-free T2 weighting and diffusion weighting imaging sequence DIADEM at ultra-high field. The VAT gradient is turned on during imaging read-out in the slice selection direction. To further increase the acquisition efficiency, we developed a blipped version of the VAT gradient and applied simultaneous multi-slice imaging, based on blipped-CAIPI. The result is distortion reduction in EPI or acceleration in DIADEM and the increased volume coverage without increasing TR.
