MRI of the lungs using hyperpolarized noble gases
The nuclear spin polarization of the noble gas isotopes 3He and 129Xe can be increased using optical pumping methods by four to five orders of magnitude. This extraordinary gain in polarizationExpand

Subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) for subintimal recanalization to treat chronic critical limb ischemia.
PURPOSE To describe the technique of subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) to improve technical success for the performance of subintimal recanalization whenExpand

Probing lung physiology with xenon polarization transfer contrast (XTC)
One of the major goals of hyperpolarized‐gas MRI has been to obtain 129Xe dissolved‐phase images in humans. So far, this goal has remained elusive, mainly due to the low concentration of xenon thatExpand

Exploring lung function with hyperpolarized 129Xe nuclear magnetic resonance
With the use of polarization‐transfer pulse sequences and hyperpolarized 129Xe NMR, gas exchange in the lung can be measured quantitatively. However, harnessing the inherently high sensitivity ofExpand
