We investigated the use of regional Faraday shielding to
help prevent loss of hyperpolarized
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.
