ABSTRACT
PET-computed tomography (CT) and SPECT/CT have been successfully integrated and translated into the clinical practice of oncology, cardiology, and neurology. They have also emerged as valuable tools for managing many other disorders, including degenerative, endocrine, and infectious or inflammatory diseases. This chapter includes a brief review of the history of PET/CT and SPECT/CT, followed by a discussion of
