Synopsis

X-nuclei MR offers unique information relating to cellular and metabolic processes in tissues. Multi-tuned coils are frequently utilised for X-nuclei measurements, and a number of novel approaches for double tuning coils exist. However, designing a well-performing multi-tuned coil is challenging, and making any improvement in SNR is particularly desirable on the X-nucleus coil due to the intrinsically lower MR sensitivity of X-nuclei. This study focuses on the insertion of double-matching networks in a single-structure, double-tuned ¹H/²³Na coil and compares their effect on the coil performance. The double-matching networks were built using either split or blocking traps.
