A Perspective of the Future of Nuclear Medicine Training and Certification.

Nuclear Medicine (NM) has evolved from a medical subspecialty using quite basic tests to one using elaborate methods to image organ physiology and has truly become "Molecular Imaging." Concurrently, there has also been a timely debate about who has to be responsible for keeping pace with all of the components of the developmental cycle-imaging, radiopharmaceuticals, and instrumentation. Since the foundation of the American Board of NM, the practice of NM and the process toward certification have undergone major revisions. At present, the debate is focused on the inevitable future convergence of Radiology and NM. The potential for further cooperation or fusion of the American Board of Radiology and the American Board of NM is likely to bring about a new path for NM and Molecular Imaging training. If the merger is done carefully, respecting the strengths of both partners equally, there is an excellent potential to create a hybrid NM-Radiology specialty that combines Physiology and Molecular Biology with detailed anatomical imaging that sustains the innovation that has been central to NM residency and practice. We introduce a few basic trends in imaging use in the United States. These trends do not predict future use, but highlight the need for an appropriately credentialed practitioner to interpret these examination results and provide value to the health care system.
