Abstract. It was created the radio physical infrastructure for 0.5 T MRI scanner Bruker Tomikon S50, designed to configure transceiver channels on Larmor frequencies of other than protons nuclei, essential for biomedical research. Thus, for the first time in world practice on the model of medical tomography, it was realized registration of NMR signals from 7 nuclei ¹Í, ²Í, ¹¹Â, ¹³Ñ, ¹⁹F, ³¹P, ²³Na and NQR signal from nucleus ³⁵Cl. It shows that the use of external and implanted passive coils tuned to the frequency selected nuclei leads to increased received signal by three orders of magnitude, allowing to record both NMR spectra and MR images.

Key words: magnetic resonance imaging, NMR spectroscopy, multinuclear applications, fluorocarbons, implanted coils.
