摘要
Positron emission tomography (PET) exploits a number of biologic tumor characteristics including glucose metabolism, cell proliferation, amino acid transport and synthesis, and hypoxia. PET using [F-18] fluorodeoxyglucose (FDG) provides more sensitive and more specific information about the extent of disease than morphologic-anatomic imaging alone and it is a powerful modality for determination of response to treatment. The metabolic information from FDG-PET is also superior compared with anatomic imaging in detecting residual viable tumor tissue after completion of treatment. Recent developments in instrumentation and the use of new tracers targeting cell proliferation and amino acid transport and synthesis hold promise to augment the application of PET in cancer patients in the future.
