Abstract
Computerized tomography (CT) is very helpful in demonstrating the presence and extent of supratentorial gliomas, particularly in combination with i.v. injection of contrast material. Certain specific density patterns existed and enabled differentiation with confidence at low grade gliomas from glioblastomas. Overlapping occurred as expected, since histological proof was sometimes obtained by needle biopsy with its inherent doubt as to true tumor representation. Future CT techniques such as sequential scanning after i.v. injection of contrast material may further increase the usefulness of CT scans in the diagnosis and therapeutic approach to the patient with a suspected glioma.
