Brachial plexus is anatomically complex and may be involved in a variety of pathologies that leads to significant morbidity. MR neurography, based on diffusion-prepared MR neurography (SHINKEI), plays a major role in the diagnostic work-up of plexus pathologies. To solve the problems that caused by the current fat suppression techniques (SPAIR and STIR) with SHINKEI, we developed motion-sensitized driven inversion (MSDI). MSDI could simultaneously suppress fat, flow and muscle signals using only one pre-pulse module. SHINKEI with MSDI provides uniform fat suppression in the brachial plexus, as in STIR, with no significant decrease in SNR compared to SPAIR.
