[Advances in cerebral angiography (author's transl)].

During recent years, catheter angiography of the cerebral vessels has tended to displace direct puncture of the carotid arteries. The method has significant advantages for the radiologist and the patient. A number of procedures are described which make this examination more easily performed, increase its diagnostic value and, most important, render it safer for the patient. Changes in catheter technique, in the radiographic apparatus and in the scope of the method are discussed.
