There are about 40,000 medical MRI systems in the world, including 6,500 in Japan. Because of the low sensitivity and functional segregations against medical X-Ray CT systems, only the visualization of ¹H proton nucleus of water and lipids contained in human patients can be clinically utilized. As for the further development of the next-generation MRI, which has now stopped due to the upper limit of static B0 magnetic field strength, the research and development of in-vivo sodium (Spin quantum number 3/2, γ = 11.26 MHz/T) aimed at clinical application of ²³Na-MRI measurement was started.
