High-resolution sodium imaging has been performed in vivo using a 4T whole-body system and a gradient echo sequence. In a monoexponential approximation T1 mapping can be performed in a manner similar to that for protons, using two gradient echo acquisitions. Careful parameter optimisation is required, as well as high SNR.
