[Techniques for the diagnosis of cerebral ischemia (author's transl)].

The various techniques for the diagnosis of cerebral ischemia are reviewed. The methods for investigating the large cervical arteries are considered (angiography, ultrasonic Döppler technique, carotid compression test) as well as those concerned with intracranial circulation. The latter are divided in "functional" methods (Rheoencephalography cerebral blood flow measurements with Xenon or with microspheres) and "morphological" methods (Brain scintigraphy and CAT scan). The respective values of the various methods are estimated in a personal series of patients.
