This concise reference text summarizes the current knowledge of nuclear medical applications in a wide range of fields, including oncology, cardiology, endocrinology, neurology, gastroenterology, urology, gynecology, and pediatrics. Besides well-established methodologies, recent developments in diagnosis (in particular the hybrid imaging techniques, PET/CT and SPECT/CT) and advances in therapy (radioimmunotherapy, radiopeptide therapies) are presented. Information is also provided on indications, procedure and medical society guidelines, diagnostic efficacy, and cost effectiveness. It is anticipated that this book will become the standard reference both for nuclear medicine physicians and for practitioners in related fields (e.g., oncologists, cardiologists, endocrinologists, and neurologists).
