Résumé : Angioscintigraphy augmented by programmed analysis of cerebral perfusion provides a technique of remarkable diagnostic accuracy which, compared to other investigations, is both simple and safe. This study shows that a 20% perfusion difference between the cerebral hemispheres indicates a vascular anomaly requiring further investigation. The examination is mainly a way of examining territories of supply by major blood vessels in cases of vascular disease. It allows the elimination of vascular lesions from diagnosis when the perfusion difference between the cerebral hemispheres is less than 20%. This is particularly helpful in cases where large blood vessel disease is suspected. © 1974 Springer-Verlag.
