This handbook, written in a clear and precise style, describes the principles of positron emission tomography (PET) and provides detailed information on its application in clinical practice. The first part of the book explains the physical and biochemical basis for PET and covers such topics as instrumentation, image reconstruction, and the production and diagnostic properties of radiopharmaceuticals. The focus then turns to the use of PET in clinical practice, including its role in hybrid imaging (PET-CT). A wide range of oncological applications in different body systems and organs are discussed, and uses of PET in cardiology, neurology, and psychiatry are also addressed. Characteristic findings are described and illustrated by numerous images, many of them in color. This book will be of value not only for nuclear medicine physicians and radiologists but also for oncologists, surgeons, cardiologists, neurologists, psychiatrists, and residents with an interest in molecular imaging.
