The task was set in an experiment on animals to check possibility of the use of the before worked out and studied methodology of intravenous insert of the standardized form water solution magnetite of nanoparticles (preparation of ICNB) for contrasting of malignant tumor at MRI research. The main purpose to change the indexes of relaxation of T1 and T2 in area of malignant tumor during realization MRI by means nanoparticles of ICNB. In investigation on animals (Vistar rats) was proof that magnetite of nanoparticles (ICNB) are contrast means for malignant tumor visualization. Was been shown that magnetite of nanoparticles have contrast effect when performing magnetic resonance .
This fact is connected with elimination the ICNB out of rats organism.
