[A comparison of various diagnostic methods in 491 cerebral tumours (gamma encephalography, cerebral angiography, pneumo-, electro-, echoenecephalograph and plain films) (author's transl)].

Isotope and neuroradiological methods were evaluated in the diagnosis of 491 surgically confirmed cerebral tumours seen between 1966 and 1973 (July). They were analysed in terms of region, type and size. The accuracy of various techniques was investigared and their value when used in isolation and in combination with other methods was calculated.
