WebMRI 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 used to evaluate: Hydrocephalus (increased brain fluid) Cases of flow obstruction, such as: Achondroplasts. Aqueductal stenosis. Normal pressure ... WebThe pulling on the sacral end of the dural membranes via the pelvic floor muscle will squeeze the CSF up the spinal canal into the brain with inspiration. This is a much stronger force than any ciliary or cardic induced influence of CSF flow. Recent MRI studies have confirmed this as well.
