It is difficult to un­ derstand and describe the meaning of this process as no other revolution has involved so many people in such a short time. In particular, the Internet is about to influence all aspects of our lives.

Also in the field of radiology, a spectacular growth took place in the last few years: in a paper published in the American Journal of Roentgen­ ology (AJR), K. W.
