CALIBRATION OF SYSTEMS MRI USING PRESET CONCENTRATIONS OF ISOTOPES F AS REFERENCE VALUE Russian patent published in 2020 - IPC G01R33/58 

FIELD: medical equipment.

SUBSTANCE: invention can be used for calibration of a magnetic resonance imaging system. Essence of invention consists in the fact that the kit for calibration of the magnetic resonance imaging (MRI) system comprises two or more objects, wherein two or more of said objects have preset concentration of isotopes ¹⁹F and matrix material, wherein isotopes ¹⁹F occur from a contrast agent, which is at least partially embedded and/or encapsulated by matrix material, and wherein two or more of said concentrations differ from each other, and wherein isotopes ¹⁹F are derived from a fluorinated contrast agent selected from a group consisting of partially fluorinated compounds of carbon, perfluoroalkylbromide and perfluoroalkyl chloride.

EFFECT: providing an agent for quantitative assessment of degree of inflammation in the given inflammatory process by MRI imaging.
