Polarization Behavior of Fluorine-Labeled Glucose-Water Solution

Magnetic resonance imaging (MRI) with contrast agents has become an indispensable tool in medical imaging. When contrast agents such as $^3$He gas, $^{13}$C in pyruvic acid, or fluorine-labeled glucose (FDG) are used in vivo, sensitivity can increase by a factor of 10,000 or more, particularly when the nuclei are dynamically polarized. This report presents the results of the first dynamic polarization experiments involving fluorine and hydrogen in a glucose solution doped with TEMPO.
