Abstract
A method for a combined air and isotope ventriculography is described. Twenty-nine infants with suspected hydrocephalus were studied. The merit of the combined study is the possibility of obtaining both anatomical and functional information. A very small amount of radioactivity—15 μc—was found to give satisfactory results. Patterns of cerebrospinal fluid flow in communicating and non-communicating hydrocephalus and in cases of porencephalic cyst and complete obstruction of the lateral ventricles are described.
