Direct arterial injection of hyperpolarized

A rat model was developed to enable direct administration of hyperpolarized Rat P22 sarcomas were implanted into the right inguinal fat pad of BDIX rats such that the developing tumors received their principle blood supply directly from the right superior epigastric artery. Hyperpolarized Intra-arterial infusion of hyperpolarized The model maximizes tumor substrate/drug delivery and minimizes T
