We investigated the use of regional Faraday shielding to help prevent loss of hyperpolarized 13 C magnetization due to premature excitation during tracer delivery and recirculation about a primary region of interest. The value of this approach was demonstrated in simulations and hyperpolarized phantom experiments.
