We propose a novel high resolution diffusion-weighted imaging sequence that combines readout-segmented (RS)-EPI and short-axis propeller (SAP)-EPI readouts. The RS-EPI image provides a high resolution diffusion-weighted image, whereas the SAP-EPI readout acts as a navigator for both the RS-EPI and SAP-EPI readout and is also used to form a second diffusion weighted image with a higher T2-weighting and thus additional diffusion-weighted contrast.
