The development of magnetic resonance imaging (MRI) will deep- ly change the relationship between neuroanatomy and the neuro- logical sciences, particularly neuroradiology. Presentation of nor- mal or abnormal brain structures is sometimes more precise in MRI sections than in brain or spinal-cord sections under macro- scopic examination. It is our conviction that a better exchange be- tween neuroanatomy and neuroradiology will improve knowledge of the brain. This international meeting held in Marseille, 26-27 September 1986 (under the Presidency of G. Lazorthes and G. Di Chiro in...

Despite all recent advances, the most important progress in neuroradiol ogy has been in our knowledge of the anatomy of the nervous system. DANDY'S injection of ventricles and cisterns with air, SICARD'S studies of the epidural and subarachoid space with lipiodol, MONIZ'S work on cerebral arteries and veins, and, more recently, DJINDJIAN'S and DI CHIRO'S investiga tions of spinal arteries, have modified, refined and expanded current knowl edge of anatomy of the central nervous system. As described by LINDGREN, "the neuroradiologist dissects the region of interest with x-rays like a surgeon...
