MRI/MRS: Use of Isotopes in Hyperpolarization

Sigma-Aldrich.com presents an article concerning MRI/MRS and the use of isotopes in hyperpolarization.

Dynamic Nuclear Polarization

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.
