During the past century, radiology has produced phenomenal research, developed sound systems of education for radiologic technologists and radiologists and established a tradition of excellence in patient care. Such advances have, in many cases, occurred only through cooperative efforts between radiologic technologists and radiologists. But health care reform looms ahead, and with it will come many uncertainties. This article examines some of the changes radiologists and radiologic technologists may experience during this period of change, including shifts in research methods, educational systems and clinical practice patterns. The author believes that as the next 100 years of our profession unfold, radiologic technologists and radiologists must work together to ensure radiology's continued growth and to protect the quality of its educational systems and its high standard of patient care.
