The main goals for the establishment of SILAN were to bring together all Spanish- and Portuguese-speaking radiologists, neurologists, and neurosurgeons devoted to the practice of the different elds within neuroradiology, to establish a professional society that could represent our particular identity and needs, and to support the professional development of its members. From the outset, there was a unanimous decision to have annual scientic meetings in different countries, alter­nating between Spain and Portugal 1 year, followed by three sequential annual meetings in different countries in Latin America. At the time, only the United States had a formally established national neuroradiological society (American Society of Neuroradiology, founded by Dr. Taveras and 23 additional founding members in NewYork City in 1964). It was the rst specic goal of SILAN to use the annual scientic meetings to foster the creation and to strengthen national neuroradiologi­cal societies in each one of the individual member countries. The second specic goal of SILAN was to bring state-of-the-art neuroradiological education to the member countries, presented preferentially in Spanish or Portuguese, the ofcial languages of the society. This was an imperative for the development of local societ­ies since language barriers made it difcult for the audiences to absorb difcult imaging or therapeutic concepts in those days. Our meetings are still conducted in Spanish and Portuguese, with the non-member guest speakers usually presenting in English, with available simultaneous translation for the participants who may need it. The third specic goal of SILAN was to develop centers of excellence in different countries where SILAN could sponsor young radiologists, neurologists, and neuro­surgeons who would compete for training scholarships in both diagnostic and inter­ventional neuroradiology, and then return to their countries of origin after completion
