Sigma-Aldrich.com presents an article concerning MRI/MRS and the use of isotopes in hyperpolarization.
Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically enhanced NMR signals for detection.
Compounds labeled with stable isotopes are used in Magnetic Resonance Imaging to render visible metabolic changes in the body. The goal of this application is the early diagnosis and treatment of neuropsychiatric disorders, cancer, and other disease states.
