By using radio-labelled tracers, four-dimensional (4D) images can be reconstructed by a computer. This computer shows the concentration and location of the tracer of interest, and noninvasively observes the changes of interesting molecular targets in living subjects. Therefore, PET plays a critical role in the era of molecular medicine because it allows for earlier diagnosis and better management of patients with various diseases, such as cancer, neurodegenerative diseases, mental diseases, and metabolic disorders. This book’s stated purpose is to provide a discussion of the technical basis and clinical applications of PET, as well as their recent progress in nuclear medicine. It also summarizes current literature about research and clinical science in PET. The book is intended not only for scientists, but also clinicians seeking recent information regarding PET imaging processing, kinetic modelling, free software, radiopharmaceuticals, clinical application, and diagnosis. The authors are qualified experts in the fields of physics, chemistry, technology, and medicine. They introduce each concept clearly, and they provide new research data and valuable experiences in their respective areas. We hope that both clinicians and scientists find this work useful and stimulating.
