[The value of the excretion urogram following cerebral angiography (author's transl)].

Routine abdominal films were obtained after 100 carotid angiograms in order to see the excretion urogram. In 64 patients the contrast was adequate for diagnosis. In twelve of these a significant finding was observed. This simple additional examination was particularly valuable in searching for a primary tumour when the angiogram had demonstrated cerebral metastases.
