New approaches to MRI on heavier than proton nuclei are considered. Re aim of using heavy nuclei visualization is to find proton-less tissues and farm-preparations inside of organism in vivo. First of all, it is important to know where fluorine contenting preparations – blood substitute Perftoran®, contrasting gases in MRI pulmonology, etc., are localized. An analogical problem has place in discovering 23Na, 13C, 31P, 2H and other nuclei in content of tissues and preparations, especially 23Na ones which influence onto blood tension level, kidney diseases, initiation of diabetes. It is interesting a production of hyperpolarized state of nuclei 129Xe, 36Kr, 3He, 13C, 29Si allowing to enhance MRI signals until 4-5 orders and provide high contrasting MRI images.
