Hyperpolarized ³He Imaging:

Hyperpolarized ¹²⁹Xe Imaging:

Dynamic images of the human lung during inhalation and expiration of ³He.

Pulmonary gas flow dynamics with hyperpolarized ³He, in the human lung using a flouroscopic imaging technique.

Interleaved 2D Spiral acquisition of 5.0 cm thick section of volunteer slowly inhaling 1.0 liter of hyperpolarized ³He gas. Time per frame = 120 ms; FOV = 50 cm
