Preferred Label : Oxygen 15-labeled Oxygen;
NCIt synonyms : O2-15; 15O-labeled Molecular Oxygen; 15O-O2; 15O2;
NCIt definition : A radiopharmaceutical comprised of oxygen-15 labeled oxygen (15O-O2) used as a tracer
molecule during positron emission tomography (PET). Upon inhalation, 15O-O2 binds
to hemoglobin in the blood and the labeled red blood cells distribute throughout the
vasculature in the body. Upon PET imaging, 15O-O2 can be used to determine both the
oxygen extraction fraction (OEF) and the metabolic rate of oxygen.;
