Stable Isotopes in PET (Positron Emission Tomography)

Labeled isotopes used as target materials in imaging have provided insights into the various mechanisms of human physiology and have lead to treatments for diseases. Water-18O is used for the production of 18F radionuclides, such as 18FDG (Fluoro-deoxyglucose). 18FDG used in PET and with other imaging technologies, such as CT/SPECT, has led to the diagnosis and treatment of a wide range of diseases, including lung, liver, and brain tumors, epilepsy, and Alzheimer’s.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
