The evaluation of ventriculography as a supplement to computed tomography

Summary The diagnostic value of ventriculography (VGR) as a supplement to computed tomography (CT) is evaluated in 42 patients. CT was slightly superior for diagnosing expanding lesions and could tell more about the size and nature of the processes in this selected material which includes only lesions adjacent to the ventricular system. VGR yielded more information about the attachment of a tumor to the wall, floor, or roof of the ventricles. Stenosis or occlusion of the Sylvian aqueduct, communicating hydrocephalus, and basal adhesive arachnoiditis were diagnosed by VGR, while the correct diagnosis could be suggested only by CT in these cases.
