OXYGEN-17

O-17 in the form of gas and water for Magnetic Resonance Imaging (MRI) and Scientific Applications

O-17

Nuclear magnetic resonance (NMR) technology is accelerating a revolution in medical imaging.

​NMR technology based on Oxygen‑17 uses the magnetic properties of atomic nuclei that occur naturally in the body. Oxygen‑17 (O‑17) is now being used for diagnostic applications and medical research to create a new generation of NMR Images.

​New developments with O‑17 enhance the quality of information about living tissue to improve the practice of medicine in the fields of cardiology and neurology among others.

​The magnetic property of O‑17 makes it to a promising tool for assessing in vivo metabolic tissue information.
