This past year was very special for radiology, one of the few medical specialties that can state precisely the date of its beginning, because 1995 was the 100th anniversary of Professor Wilhelm Conrad Röntgen's discovery of the X ray in a physics laboratory in Würzburg, Germany. This centennial was celebrated with special lectures, presentations, and exhibits throughout the world by radiologists, scientists, and their colleagues.
