Isotope cisternography and ventriculography in congenital CNS anomalies.
Isotope studies are well-tolerated examinations in various congenital CNS anomalies and are valuable in demonstrating the presence of associated hydrocephalus, abnormal accumulation of isotope associated with abnormal CSF flow or a failure of absorption. In some cases these studies may be of differential diagnostic value and a helpful indicator in the choice of surgical treatment. These tests do not disturb the CSF equilibrium which is often observed following air or other contrast studies.
