Deuterium Metabolic Imaging (DMI) is a new technique, which could potentially be used to study liver metabolism in vivo. The aim of this study was to develop a 4-channel 2H transmit/receive array for DMI of the liver at 7T, combined with 4 1H dipole elements for conventional anatomical MRI. Natural abundance DMI water and lipid maps measured on a phantom showed good correspondence with 1H Dixon water and lipid images. The multi-channel setup allowed us to pick up the natural abundance 2H water signal throughout the whole liver in a 3D DMI acquisition with a nominal resolution of 20x20x20 mm3.
