The presented work shows the robustness of pure phase encode MRI to B0 field inhomogeneity by showing 3D SPRITE phantom images of samples with significant metal content. The paper also outlines the robustness of SPRITE to the gradient eddy currents induced by switching pulsed field gradients, which has enabled new high pressure MRI study inside metallic containers at variable temperature and pressure condition. An eddy current self-compensated SPRITE sequence allows us to acquire geometrically correct images inside highly conductive cylindrical metal containers.
