    摘要: A dispenser (132), a magnetic resonance imaging system (100), and a method for using hyperpolarized contrast agent (304) during a magnetic resonance imaging examination. The dispenser comprises an attachment component (136) for a face piece (138). The face piece is adapted for receiving the surface of a subject (114) such that when the subject inhales hyperpolarized contrast agent enters the respiratory system of the subject. The dispenser further comprises a reservoir (300) adapted for receiving the hyperpolarized contrast agent. The dispenser further comprises a gas flow (406) tube connected to the attachment component and a vaporizer (406, 408, 412, 510, 602, 606) for vaporizing the hyperpolarized contrast agent in the gas flow tube into a hyperpolarized vapor. The dispenser further comprises a controller (402) for controlling when the vaporizer vaporizes the hyperpolarized contrast agent.
