Case Presentation Magnetic resonance imaging (MRI) using a time-spatial labeling inversion pulse (Time-SLIP) method permits visualization of cerebrospinal fluid (CSF) dynamics noninvasively. Time-SLIP enables quantitative and qualitative CSF flow analysis without any limitations in flow velocity or direction. An 85-year-old old male: Syringomyelia (C7-T12) Conventional MRI revealed syringomyelia with multiple syrinx cavities. Time SLIP can detect the CSF flow dynamics in both the intra- and peri-spinal cord simultaneously. The basic CSF flow pattern in the syringomyelia cavity was pulsatile motion in the Cranio-caudal direction and harmonious with the flow in subarachnoid space (Figure 1). Time-SLIP also detected over flow through septum or web. The unique flow across the intramedullary compartments indicated several paths throughout the septum of syrinx (Figure 2). These findings may improve our understanding of disease pathology of syringomyelia and be useful in surgical planning
