Initial 23Na MR images of the human torso acquired at 3-Tesla using an 8-channel dual tuned 23Na/1H transmit/receive coil after RF inhomogeneity corrections are presented. 23Na images were obtained with 0.3 cm spatial resolution and ~20 SNR in ~15 min with clear delineation between different abdominal organs and their sub-regions. These images were acquired with imaging parameters optimized under SAR limits for human scans. The ability to perform 23Na MRI in clinical settings is useful to non-invasively detect and diagnose diseases in various body organs due to the physiological significance of trans-membrane sodium gradient that is critical for cell survival.
