Deuterium magnetic resonance measurements are of growing interest in the field of metabolic imaging. Four subjects were loaded with D2O to ~1.5% enrichment over a 6-week period for a parallel study of immune cell proteomics. We report T1 and T2* relaxation times of deuterium in HDO measured from cerebral spinal fluid (CSF), white matter (WM) and grey matter (GM) in vivo, using a 7T Philips Achieva scanner with a dual-tuned 2H/1H birdcage coil. 2H T1 values are significantly shorter than corresponding values for 1H in H2O, due to the quadrupolar 2H relaxation, whilst T2* values are comparable to 1H values.
