This book describes the various contributions of positron emission tomography (PET) to the management of Hodgkin lymphoma and considers key issues in its use. A full explanation of the value of PET in disease staging and restaging is followed by discussion of its role in guiding individualized, response-adapted therapy in both early and advanced disease based on assessment of treatment sensitivity. Further chapters explore in detail the current application of PET for determination of tumor metabolic volume and planning of involved field radiotherapy. The book concludes by discussing PET scan reporting in clinical practice and the rules that have now been formally set following a number of international workshops designed to develop standard reporting criteria based on expert agreement. The authors are leading authorities who adopt an interdisciplinary approach in covering the most important aspects of the use of PET in Hodgkin lymphoma in a readily understandable way.
