Inadequate production or too-rapid absorption of CSF. A tear in the dura mater surrounding the brain and spinal cord. The dura mater can become torn, causing CSF to leak out, for one of several reasons.
WebCerebrospinal fluid (CSF) flow MRI is used to assess pulsatile CSF flow both qualitatively and quantitatively. Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis.
