We reported a technique to visualize the irregular flow of cerebrospinal fluid (CSF) by using dynamic improved motion-sensitized driven-equilibrium steady-state free precession (dynamic iMSDE SSFP). The purpose of this study was to investigate the characteristics of intracranial CSF visualization with dynamic SSFP using acceleration selective motion sensitized gradient (AS-MSG). The dynamic SSFP using AS-MSG distinguished acceleration flow in CSF from constant flow. This technique is suggested to contribute to the diagnosis of various diseases in the CSF space.
