ABSTRACT Purpose To develop and evaluate an 2 H/ 1 H coil configuration that enables deuterium metabolic imaging at 7 T while preserving high‐quality 1 H anatomical imaging. Methods An 16‐channel 2 H high‐impedance receive array was combined with a 2 H transmit birdcage and a 16‐channel dual‐row 1 H transceiver array. Electromagnetic simulations are used to assessed B 1 + 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.
