Abstract:
A container for receiving a quantity of hyperpolarized gas therein, comprising:at least one resilient wall comprising inner and outer surfaces which defines an expandable chamber for holding a quantity of hyperpolarized gas therein; a quantity of non-toxic hyperpolarized fluid held in said expandable chamber, wherein said inner surface of said wall is configured such that said inner surface inhibits contact-induced polarization loss of said hyperpolarized fluid, and wherein said wall is configured to inhibit the migration of oxygen into said expandable chamber; a port in fluid communication with said expandable chamber; and sealing means operably associated with said port for controlling the introduction and release of said quantity of hyperpolarized fluid into and out of said expandable chamber; wherein the T1 for said hyperpolarized fluid held in said container resulting from one or more of contact-induced polarization loss and oxygen migration into said chamber is greater than about 6 hours.
