Correction of susceptibility-induced GRE phase shift for accurate PRFS thermometry proximal to cryoablation iceball

Abstract

The susceptibility contrast between frozen and unfrozen tissue disturbs the local magnetic field in the proximity of the ice-ball during cryotherapy. This effect should be corrected for in real time to allow PRFS-based monitoring of near-zero temperatures during intervention.
