The cerebrospinal fluid flow imaging has been used to diagnose several diseases in the clinical practice. In this study, we developed a sequence with multiple flexible labeling bands to visualize the CSF flow based on the concept of time-spatial labeling inversion pulse. Phantom study and human study were both done at a 3.0T scanner. The sequence can image the CSF flow of the aqueduct and foramen magnum simultaneously and improve the scan efficiency.
