Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS) with nuclei different from protons, often require the acquisition of proton signal for shimming and co-registration procedures. For this purpose Double Tuned Radio Frequency (DT-RF) coils are needed. The drawback of DT-RF coils is basically the coupling between the two resonant structures, which reduces SNR and increases focal heating. The aim of this study is to compare active and passive decoupling strategies in terms of Q factor and S21 parameter. Workbench measurements show that PIN Diode active decoupling is an interesting alternative for DT-RF coils.
