A Stejskal-Tanner diffusion preparation with a GRAPPA-accelerated vGRASE acquisition is proposed. Compared to conventional ss-EPI, vGRASE is less sensitive to off-resonance effects despite being a single-shot technique and hence also robust to motion. With sequence modifications and phase correction techniques we adress problems induced by the diffusion gradients.
