MRI has potential advantages for diagnostic imaging near metallic implants compared to other modalities, but can suffer from severe artifacts caused by implant-induced inhomogeneities. MAVRIC is one of the recently developed MRI techniques for this application. A main challenge to MAVRIC, however, is prolonged scan time. In this work, we investigated the performance of parallel imaging methods in the presence of significant off-resonance and signal distortion caused by metal implants. We demonstrate that parallel imaging can effectively be combined with MAVRIC for imaging near metallic implants in reduced scan times.
