A few years ago, at the Symposium of Neuroradiology in Rome, ZIEDSES DES PLANTES made a decisive contribution to cerebral angiography with photographic subtraction. From this time on, technical advances, anatomical findings, therapeutic tests such as embolization, development of stereo­ taxy, and computerized axial tomography have opened a wide field for cerebral angiography. These important findings became the subject of a scientific meeting. The quality of the presentations and the results of each re­ port made this a most interesting symposium. I am very grateful to all those who contributed to make it a success. G. SALAMON Marseille, October 10th 1975 v This meeting was held under the guidance and with the financial help of INSERM (Paris) . We also thank the Ministry of Foreign Affairs Faculty of Medicine in Marseille Administration of the Hospital in Marseille CGR, Kodak, Guerbet, Philips and Siemens for their material support.
