Motivation: 2H and 31P MRSI provide relevant biomarkers, yet suffer from long scan time, low sensitivity and hardware swaps. With a novel setup, hardware swaps are avoided, facilitating interleaved scanning of 31P and 2H metabolites.
Goal(s): The goal of this study was to design the novel hardware and assess the feasibility of gaining SNR using an interleaved 31P and 2H MRSI acquisition.
Approach: Lossless filters were developed to merge the 2H and 31P setups and were tested on a healthy volunteer.
Results: Interleaved scanning is possible and increases SNR of 31P and 2H signals in the liver.
Impact: Lossless RF filters enable interleaved 31P and 2H MRSI acquisitions employing a double tuned bore coil and body receive array. This results in substantially improved SNR of metabolite signals from both nuclei, obtained in less examination time.
