A variety of enhancements to the MAVRIC technique are described and demonstrated to produce minimal artifact images with sub-millimeter resolution in the near vicinity of total joint replacements. Clinically feasible scan times are achieved by using k-space corner-cutting, partial Fourier, and autocalibrated parallel imaging undersampling acquisition strategies. MAVRIC images are shown to dramatically reduce susceptibility artifacts while maintaining diagnostically relevant spatial resolution when compared to established 2D-FSE arthroplasty images.
