The aim of this study was to compare different EPI-based MR sequence techniques (conventional EPI, zoomed EPI, readout-segmented EPI and integrated 2D shim EPI (iShim)) for diffusion weighted imaging of the neck at 3 Tesla. To this end, MR measurements of a dedicated phantom and in-vivo measurements in volunteers were performed.

Our results suggest that iShim is the best option for DWI of the neck at 3 Tesla yielding good image quality and efficiently reducing spatial distortions and off-resonance artifacts.
