Applications: 18O2 is used in positron emission tomography (PET) as a precursor to fluorodeoxyglucose (FDG). H2O18 is blasted with hydrogen ions to create F-18, which is then synthesized into FDG and injected into a patient. Images of specific organs can then be viewed using PET. Also used to measure energy expenditure in humans. It also has applications as a tracer molecule in material science and in plant biology.
