OXYGEN-18

O-18 in the form of water for Medical Applications

O-18

Oxygen-18 is used to create tailored organochemical compounds labelled with the radio isotope F-18 (for example, 2-fluoro-2-deoxy glucose). These are used for Positron Emission Tomography (PET), the latest cancer diagnostic technique.
