PET in Abdominal Imaging of Tumors and Infections
Positron emission tomography (PET) is recognized as a powerful imaging research tool, for which the number of clinical applications significantly increased in recent years. Based on pathophysiological and biochemical principles, functional PET imaging makes it possible to assess parameters of tumor biology not easily accessible to conventional imaging such as metabolic activity, proliferation, adrenergic transmitter uptake or accumulation of cytostatics in individual tumor manifestations. For clinical applications, PET imaging with 2-[18F] fluorodeoxyglucose (FDG) is of paramount importance. This chapter reviews recent developments in the use of FDG-PET in diagnosing abdominal malignant tumors and imaging inflammatory lesions.
