Dynamic MRI of Cerebrospinal Fluid in Children

  • Francis Brunelle


The flow of cerebrospinal fluid (CSF) is a dynamic phenomenon, as reported in other chapters of this book. The net flow is small and is difficult to measure noninvasively. Most diseases involving the CSF are due to an anomaly in the dynamics of its flow. Until now the diagnosis of CSF pathology was based on the morphology of the CSF-containing spaces. CT and MRI can demonstrate the ventricular and subarachnoid spaces. Several indexes have been published, but subtle changes are difficult to assess. Moreover, ventricular shape and volume do not correlate with the pressure and circulation of the CSF. A fruitful comparison is with the physiology of the heart: no cardiologist today would try to assess heart function on the basis of the size of the heart as seen on a plain film of the thorax.
