18O in the form of water for Medical Applications
Oxygen-18 is used to create tailored organochemical compounds labelled with the radio isotope 18F (for example, 2-fluoro-2-deoxy glucose [18FDG]). These are used for Positron Emission Tomography (PET), the latest cancer diagnostic technique.
Our Oxygen-18 products are manufactured in accordance with cGMP regulations and with the requirements of 21 Code of Federal Regulations: PARTS 210 and 211
