Purpose:
To develop and evaluate an 2H/1H coil configuration that enables deuterium metabolic imaging at 7 T while preserving high-quality 1H anatomical imaging.
Methods:
An 16-channel 2H high-impedance receive array was combined with a 2H transmit birdcage and a 16-channel dual-row 1H transceiver array. Electromagnetic simulations are used to assessed B1 + efficiency and SAR. Phantom and in vivo experiments were performed on a Philips 7T system to evaluate transmit efficiency, signal-to-noise ratio, and signal coverage.
Results:
Simulations results match with experimental ones, and they demonstrated good transmit efficiency, receive sensivity and image quality. In vivo 2H 3DMRSI map demonstrated whole brain coverage.
Conclusion:
The proposed coil configuration enables robust 2H metabolic imaging at 7T while preserving good 1H performance.
