title: [Evaluation of gammagraphy in the differential diagnosis of cysts and renal tumors].
abstract: In view of the problems posed by the diagnosis of intrarenal masses, the authors review 16 cases of patients with this pathology who have undergone renographic and gammagraphic studies. They obtain a high level of coincidence between the gammagraphic diagnosis and its subsequent surgical confirmation, a fact which indicates that the kidney gammagraph is of great diagnostic value. This may be due to the different vascularization of the pathological area which would allow for a greater indication by the tracer, rejecting the theory of parenchymatous intoxication by toxic tumour substances.
