At ultrahigh fields, to achieve ultimate receive performance, the optimal current patterns go beyond the uniform current of loops. A dipole-like current is desired and can be realized by directly adding dipole antennas or by inducing dipole-mode in loops. In this work, we investigated the receive performance of different kinds of arrays with self-decoupled loops (SDLs) or/and self-decoupled folded dipoles (SDFDs). These coils have dipole-like as well as loop-like patterns and are highly isolated. We found that the combination of SDL and SDFD exhibits considerable improvement for both peripheral/central SNR and parallel imaging, even compared to mixed loop+dipole arrays.
