The MAVRIC Multi-Spectral Imaging technique acquires 4D datasets, resolving spins around metal implants in space and Larmor frequency offset. Here, we demonstrate a novel processing technique that extracts phase-contrast images from conventional MAVRIC acquisitions. Dominant trends induced by metal hardware in the phased images are removed to reveal underlying tissue with phase-contrast. The presented method may offer a means to differentiate types of adverse tissue responses near metal implants.
