      abstract     = {To measure sodium relaxation times and concentrations in
                      human wrists on a clinical magnetic resonance imaging (MRI)
                      scanner with a density-adapted radial sequence.Sodium MRI of
                      human wrists was conducted on a 3T MR system using a
                      dual-tuned 1H/23Na surface coil. We performed two studies
                      with 10 volunteers each investigating either sodium T1
                      (study 1) or sodium T2* (study 2) relaxation times in the
                      radiocarpal joint (RCJ) and midcarpal joint (MCJ). Sodium
                      concentrations of both regions were determined.No
                      differences for transversal of longitudinal relaxation times
                      were found between RCJ and MCJ
                      (T2,s*(RCJ) = (0.9 ± 0.4) ms;
                      T2,s*(MCJ) = (0.9 ± 0.3) ms;
                      T2,l*(RCJ) = (14.9 ± 0.9) ms;
                      T2,l*(MCJ) = (13.9 ± 1.1) ms;
                      T1(RCJ) = (19.0 ± 2.4) ms;
                      T1(MCJ) = (18.5 ± 2.1) ms). Sodium concentrations
                      were (157.7 ± 28.4) mmol/l for study 1 and
                      (159.8 ± 29.1) mmol/l for study 2 in the RCJ, and
                      (172.7 ± 35.6) mmol/l for study 1 and
                      (163.4 ± 26.3) mmol/l for study 2 in the MCJ.We
                      successfully determined sodium relaxation times and
                      concentrations of the human wrist on a 3T MRI scanner.},
