The UW Department of Radiology welcomes Dr. Elias Zerhouni, director of the National Institutes of Health, to inaugurate this important lecture honoring Dr. Albert A. Moss' contributions to radiology.   Dr. Zerhouni addresses the tremendous impact biomedical imaging has had on medicine and biology over the last 30 years. He also discusses a new era of biomedical imaging where technologies are developing at a rapid pace, opening up unprecedented opportunities for research and clinical applications, from molecular/cellular imaging to functional brain mapping. Dr. Zerhouni feels strongly that advancing biomedical imaging is essential for improved understanding of biological systems, detecting and controlling diseases, and enhancing human health by effectively translating research results to patient applications. Finally, he talks about the unique position the NIH is in to catalyze new scientific knowledge and revolutionary methods of research to facilitate new approaches for transforming medicine in the 21st century. Dr. Zerhouni was the chairman of Radiology at Johns Hopkins University before being appointed by President Bush as director of the National Institutes of Health. He has implemented major initiatives such as the Roadmap for Medical Research, has doubled the NIH budget, and enhanced leadership of the nation''s top medical research agency. His research in imaging has led to advances in Computerized Axial Tomography (CAT scanning) and Magnetic Resonance Imaging (MRI) that resulted in 157 peer reviewed publications and 8 patents.
