Dynamic improved motion-sensitized driven-equilibrium steady-state free precession (dynamic iMSDE SSFP) has been introduced to visualize the irregular flow of cerebrospinal fluid (CSF), which obtains this data in 2D. To improve visibility of CSF space at a wide range, we here proposed a new technique using 3D-free factor. The results showed that fluid motions were sensitively suppressed by iMSDE, similar to 2D acquisition. Thus, this technique may detect irregular CSF motion at the wide range.
