This indispensable volume brings together authoritative, up-to-date, critical accounts of the present status of positron emission tomography (PET) in the study of movement disorders both in terms of the basic science relevant to PET and the clinical science related to the study of specific disease processes. For better understanding, it includes a review of the basic principles of PET and tracer kinetics. It also reviews clinical studies concerning Parkinson's and Huntington's disease, as well as some of the less common movement disorders such as progressive supranuclear palsy, olivopontocerebellar atrophy, and dystonia. Throughout the text, it emphasizes PET as a tool for the quantitative measurement of meaningful biochemical and physiological processes. This state-of-the-art work provides a perspective concerning the degree to which PET studies have advanced knowledge and the future role anticipated for PET. All clinical and basic researchers interested in functional imaging with PET and movement disorders will find this book an absolute must.
