The hyperpolarization creates a large signal intensity, and the wide range of chemical shifts allows for identifying when the 129 Xe associates with molecules like hemoglobin. 129 Xe is preferred over 131 Xe for MRI because 129 Xe has spin 1/2 (compared to 3/2 for 131 Xe), a longer T1 , and 3.4 times larger gyromagnetic ratio (11.78 MHz/T).
Hyperpolarization machines are currently being used to develop hyperpolarized xenon gas that is used as a visualization agent for the lungs. Xenon-129 is a safe inert noble gas that can be used to quantify lung function. With a single 10-second breath hold, hyperpolarized Xenon-129 is used with MRI to enable 3-dimensional lung imaging.

Hyperpolarized carbon-13 MRI is a functional medical imaging technique for probing perfusion and metabolism using injected substrates.. It is enabled by techniques for hyperpolarization of carbon-13-containing molecules using dynamic nuclear polarization and rapid dissolution to create an injectable solution.
Hyperpolarization is the process of aligning the nuclear spins in a gas, such as 3 He or 129 Xe, in the same direction to create a strong signal for imaging. To accomplish this, angular momentum is added to the system through the use of circularly polarized laser light.
Dynamic nuclear polarization (DNP) is one of several hyperpolarization methods developed to enhance the sensitivity of nuclear magnetic resonance (NMR) spectroscopy.While an essential analytical tool with applications in several fields, NMR’s low sensitivity poses major limitations to analyzing samples with low concentrations and limited masses and volumes.
