Magnetic Resonance Imaging & Magnetic Resonance Spectroscopy

Compounds labeled with stable isotopes, such as D-Glucose-113C are used in Magnetic Resonance Imaging (MRI) techniques to render visible metabolic changes in the brain. The goal of this research is the early diagnosis of neuro-psychiatric disorders.

Researchers are also currently exploring the use of helium-3, oxygen-17, and xenon-129 gases to improve lung imaging. They are also using carbon-13 and deuterium labeled products to help elucidate metabolic pathways. Isotopic labeling provides better resolution and sensitivity than natural abundance in many imaging experiments, and the use of stable isotopes in MRI/MRS techniques is increasing. ISOTEC provides the highest enrichment and largest selection of stable isotopically labeled products for all MRI/MRS applications.
