[Gamma-ray angioencephalography and computerized tomography of the brain in tumoral pathology. Comparative results].

Gamma-ray angioencephalography and computerized tomography (CT) were used to explore 151 patients with suspected intracranial tumour. The reliability of each method for the aetiological, topographical and pathological diagnosis was evaluated. The results obtained showed that the two methods correlated well and supplemented each other, bringing the proportion of positive diagnosis of intracranial tumour to more than 90%. While CT remains the first-choice examination to detect expansive lesions, gamma-ray angioencephalography represents the finest physiopathological approach and provides the most precise information on the nature of the tumour.
