Advancing Nuclear Medicine through Innovation THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Advancing Nuclear Medicine through Innovation Preface It has been an honor and a privilege to chair the committee on the state of science in nuclear medicine. As a diagnostic radiologist, a clinician-scientist, and the chairperson of a large academic radiology department, I have been exposed to the many advances in nuclear medicine and have observed their clinical benefits up close. Participating in this review, however, has allowed me to step back and appreciate the magnitude of the progress that has been achieved, and the crucial role that government funding has played in it. Investments in chemistry, physics, engineering, and training are responsible for the state-of-the-art radiopharmaceuticals and imaging instruments that we now rely on to improve our understanding of human physiology through non-invasive disease detection and treatment monitoring. These advances have already had a major impact on all branches of imaging and medicine, yet, they pale in comparison to those on the horizon. Nuclear medicine offers a unique, non-invasive view into intracellular processes and enzyme trafficking, receptors and gene expression, and forms the theoretical and applied foundation for molecular medicine. The contributions of nuclear medicine are creating the possibility of a future of personalized medicine, in which treatments and medications will be based on an individual’s unique genetic profile and response to disease processes. Although the progress in nuclear medicine research in the United States has been spectacular, potential obstacles to its continuation have been noted in previous reports, including a critical shortage of chemists and other personnel trained in nuclear medicine, and an inadequate supply of

Advancing Nuclear Medicine through Innovation radionuclides for research and development. In addition, uncertainty has arisen about how, and to what degree, the government should continue to fund nuclear medicine research. For years, the basic chemistry and physics research behind the growth of the field has been supported by the Medical Applications and Sciences Program of the Department of Energy (DOE) Office of Biological and Environmental Research. However, the uniqueness of this program relative to the nuclear medicine research funded by the National Institutes of Health (NIH) has long been under debate. The DOE and the NIH commissioned this study on the state of the science in nuclear medicine because of the uncertainty surrounding the support of the Medical Applications and Sciences Program. Specifically, the sponsoring agencies asked that the National Academies assess areas of need in nuclear medicine research, examine the program and make recommendations to improve its impact on nuclear medicine research and isotope production. In response to this request, the National Research Council of the National Academies appointed a committee of 14 experts to carry out this study. The committee gathered information from members of the public, experts on nuclear medicine, scientific and medical societies, and federal agencies. In composing its report, the committee decided to describe the needs in nuclear medicine research primarily in terms of future opportunities in the field. Thus the report, in my view, is an exciting, forward-looking document that makes clear the potential of the field for further advancing medicine, and suggests practical steps to facilitate progress. I hope and believe that it will have a positive impact on the future of nuclear medicine. Hedvig Hricak, Chair

Advancing Nuclear Medicine through Innovation Acknowledgments The committee is grateful to the speakers and panelists (listed in Appendix A) who participated in the information-gathering sessions for the study. In addition, the committee wishes to thank Belinda Seto, Peter Preusch, and Dan Sullivan at the National Institutes of Health (NIH); and Mike Viola, John Pantaleo, Prem Srivastava, and Peter Kirschner at the Department of Energy (DOE) for contributing their time, efforts, and insights to the study. I would like to personally thank my fellow committee members for their dedication to carrying out a thorough study and writing a useful report. They all cared deeply about the topic, and their probing questions and lively discussions ensured that we covered a wide range of issues and considered them from multiple angles. Studies such as this are often long on information and short on time, and the committee would like to thank the many National Research Council staff members whose help was essential in producing this report. Among these, the committee particularly wishes to acknowledge Kevin Crowley, Director of the Nuclear and Radiation Studies Board, for providing guidance on the study process and keeping the committee focused on its charge; Shaunteé Whetstone and James Yates for their administrative support; Toni Greenleaf for making sure that we stayed on budget; and Rick Jostes for his technical contributions to the report. I would especially like to thank the
