We assessed whether diffusion-weighted reversed fast imaging with steady-state precession (DW-PSIF) can demonstrate cerebrospinal fluid flow. DW-PSIF showed signal reduction at the cerebrospinal fluid (CSF), which was corresponded to CSF flow on phase-contrast imaging. DW-PSIF with higher moment revealed less imaging quality and less signal-to-noise ratio. DW-PSIF can be a method to assess CSF flow in a relatively good imaging quality and in a short time.
