[The diagnostic value of CT and angiography in cerebral tumors (author's transl)].

In a cooperative study the examination results of CT and angiography of 756 patients with verified supratentorial tumors were compared. CT displayed the higher diagnostic accuracy. Temporobasal tumors cause diagnostic problems for both examination methods. The value of arteriography is still unquestioned because using this examination method the differential diagnosis of mass lesions can be considered largely secured.
