WebMRI with CSF Flow MRI of the brain or spine that evaluates the flow of cerebral spinal fluid (CSF) around the brain, brainstem or spinal cord. For patient preparation, please visit MRI Brain. MRI Brain with CSF flow is … WebCONCLUSIONS: Both fast cine-PC and pencil-beam imaging demonstrated expected changes in CSF flow with Valsalva maneuver in healthy participants. The real-time capability of pencil-beam imaging may be necessary to detect Valsalva-related transient CSF flow obstruction in patients with pathologic conditions such as Chiari I malformation.
