This research employs a navigated multi-shot DWI, termed Navigator-MUSE, to enhance image quality. This novel 16 shot DWI technique is capable of improving spatial resolution (0.8 x 0.8 x 0.8 mm3) while also eliminating aliasing artifacts and geometric distortions. We demonstrate that Navigator-MUSE is capable of minimizing aliasing artifacts due to brain pulsation in highly susceptible regions like the brain stem without significant scan-time penalties.
