Dear Honorable Delegates,

Our warmest greetings from Taipei!

The upcoming XXI Symposium Neuroradiologicum will grace springtime Taipei, at the International Convention Center, between March 19-23, 2018. It is co-hosted by the Japanese Society of Neuroradiology, the Korean Society of Neuroradiology, and Head & Neck Radiology.

The theme of the upcoming symposium, “One World, One Family,” illustrates our belief that the event in Taipei will be a game-changer: since the first assembly in Belgium 1939, only a handful of events were hosted outside the European continent. But with Taipei - one of Asia's most enchanting capital cities - organizing the XXI Symposium, you can anticipate stimulating sessions, hands-on workshops, speeches by acclaimed national and international speakers, and an exciting itinerary of social events.

Further, neuroradiologicum has an abiding tradition of recognizing that excellence in this specialty could only progress with concerted effort of sharing perspectives, the latest findings, and cutting-edge technologies that cover all aspects of the specialty; thus the chosen theme: "One World, One Family," to underpin the spirit of the symposium in Taipei.

Now, our sincerest welcome to all of you to Taipei, a city that makes sense all that is contrastive yet wonderful: here, you can expect the world's most advanced metro systems, and cultural marvels that date back thousands of years ago; what is more, you will be blown away by Taipei's jaw-dropping culinary diversity, where food is considered a religion. The city is also home to some of Asia's most tourism-worthy destinations; along your travels, you can sample Taipei citizens' hospitality that international bloggers rave about.

Finally, our greatest appreciation for the encouragement of the neuroradiological communities worldwide. Your support has given us a strong foothold in the international Neuroradiological medical profession; your participation, therefore, will be key to the success of XXI Symposium Neuroradiologicum.

We look forward to seeing you in Taipei!
