Isotope Cisternography and Ventriculography

Abstract
Isotope cisternography and ventriculography have proved to complement other accepted radiological examinations in establishing a primary diagnosis of hydrocephalus in infants. The former provides an acceptable and valuable screening test for evaluating suspected compensated hydrocephalus without altering established cerebrospinal fluid equilibrium. The patency of a ventriculoatrial shunt is easily and safely demonstrated by these investigations; whether or not there is further need for the shunt may be established. Criteria for interpreting findings are stated; the safety and advantages of the tests are enumerated.
