32767-18-3 - Reference Information
| Introduction | oxygen -18 is a natural isotope of oxygen. As a "labeled atom", oxygen -18 is widely used in chemistry, medicine, biological engineering, environmental science, geology and other disciplines. It reacts with hydrogen to produce heavy water, and heavy oxygen has the properties and characteristics of oxygen. |
| Use | oxygen -18 is the production of fluorodeoxyglucose (FDG) for positron emission tomography (PET) important precursors. In general, in the radiopharmaceutical industry, concentrated water (H218O) is bombarded with hydrogen ions in a cyclotron or linear accelerator to produce fluorine -18. FDG is then synthesized and injected into the patient. When combined with tritium (Hydrogen -3), it can also be used to make a very heavy water: 3H218O or T218O. It is also primarily used for isotope tracing. |
