Nuclear cardiology is clearly a well-recognized and established clinical discipline and has been so for at least 40 years. The clinical discipline emerged from the research domain in the late 1970s and has been utilized worldwide for decades. Parallel with nuclear cardiology’s growth has been the evolution of the American Society of Nuclear Cardiology as a distinct and important entity, as well as the growth of the Journal of Nuclear Cardiology as a superb medical publication. Having had the opportunity to observe this evolution from its inception has been extremely satisfying.
