Both the MAVRIC and SEMAC methods have been shown capable of significantly reducing susceptibility artifacts near metallic implants. Here, we demonstrate that advantageous features of both methods can be utilized in combination. In particular, the z-selectivity of the SEMAC can be interfaced with the encoding mechanisms and spectral overlap utilized by MAVRIC. In doing so, a technique that offers increased volume selectivity while maintaining smooth spectral image combinations is demonstrated. Demonstrations of this hybrid approach on phantom and in-vivo implant scenarios are presented.
