PET and SPECT are two of today's most important medical-imaging methods, providing images that reveal subtle information about physiological processes in humans and animals. Emission Tomography: The Fundamentals of PET and SPECT explains the physics and engineering principles of these important functional-imaging methods. The technology of emission tomography is covered in detail, including historical origins, scientific and mathematical foundations, imaging systems and their components, image reconstruction and analysis, simulation techniques, and clinical and laboratory applications. The book describes the state of the art of emission tomography, including all facets of conventional SPECT and PET, as well as contemporary topics such as iterative image reconstruction, small-animal imaging, and PET/CT systems. This book is intended as a textbook and reference resource for graduate students, researchers, medical physicists, biomedical engineers, and professional engineers and physicists in the medical-imaging industry. Thorough tutorials of fundamental and advanced topics are presented by dozens of the leading researchers in PET and SPECT. SPECT has long been a mainstay of clinical imaging, and PET is now one of the world's fastest growing medical imaging techniques, owing to its dramatic contributions to cancer imaging and other applications. Emission Tomography: The Fundamentals of PET and SPECT is an essential resource for understanding the technology of SPECT and PET, the most widely used forms of molecular imaging.•Contains thorough tutorial treatments, coupled with coverage of advanced topics•Three of the four holders of the prestigious Institute of Electrical and Electronics Engineers Medical Imaging Scientist Award are chapter contributors•Include color artwork

Biochemical Actions of Hormones, Volume IX is an 11-chapter text that provides the developments in the theoretical and experimental understanding of hormonal actions and regulation. After presenting an overview of research on peptide and steroid hormones, this volume goes on exploring the lipotropins and their active degradation products, as well as the adenylate cyclase enzyme regulation by adrenergic receptors. These topics are followed by discussions on the potassium ion conductance in the pancreatic beta cell; the concept of the insulin sensitive chemoreceptor of the central nervous system; the estrogen-induced growth factors and their role in tumor cell growth; and the nuclear acceptors for the avian progesterone receptor. Other chapters consider the structural aspects of steroid hormones and their receptors, with an emphasis on the importance of pyridoxal phosphate research studies on a better understanding of the steroid receptors function. This book also looks into an affinity label for glucocorticoid receptors and the development of a polyclonal antibody for this receptor. The concluding chapter emphasizes the regulation of the steroid sulfotransferases. This volume will be of great value to biologists, biochemists, and researchers who are interested in the biochemical aspects of hormones.
