According to a statement of Gordon Moore, the founder of Intel Corporation, computer performance doubles every 18 months. So it is not surprising that the "half-timea of modern computers is rapidly decreasing, meaning computer based radiology equipment ages very fast. Increasing demands of public health for radiology together with a never-ending rapid development of information technology and innovations result in a digital environment, where careful and thorough guidance is necessary. The book "Digital (R)evolution in Radiologya (2001), edited by Walter Hruby, MD, is such a solid guidance for radiologists and other medical staff working in this field. As Jack I. Eisenman, MD, puts it in his review of this book, "The editor and the authors are authorities who have contributed to adapting, in a user-friendly manner, the digital (r)evolution to the needs of people who operate medical information systemsa (Radiology, April 2002). Almost three years after the first edition Walter Hruby presents the second edition. The book has not only been brought up-to-date, it also has been thoroughly revised and new aspects have been incorporated that focus on the synergy that results from the integration of digital systems used in radiology such as image fusion, "functionala imaging, electronic patient records and health networks, medical chip cards etc. It is intended for radiologists and all other physicians, as well as technicians, scientists, IT-experts, health care providers and health maintenance organisations. The IT-market now has changed to such an extent, that the Integrated Health Care Enterprise becomes reality. So the second edition of "Digital (R)evolution in Radiology" - subtitled "Bridging the Future of Health Carea - provides solid guidance for everyone working in this field.
