Nuclear magnetic resonance method for observation of ferromagnetic pulmonary contaminants

Description

A method is proposed for measurement of tissue concentration of asbestos and other contaminants containing magnetite. The method uses nuclear magnetic resonance (NMR) of protons as a means of detection of the magnetic particles present in the dust. Results of the study of the effect of concentration of iron particles and particle size on the NMR signal are presented. The NMR signal had linear relationship to the concentration particles. Experiments with different particle size indicated that the signal was proportional to the mass of particles rather than to their number. Quantitative detection of 7RF02 chrysotile asbestos in gel and in rat lungs was demonstrated
