Synthesis of Iron-nickel Particles by Co-precipitation Technique and Used as a Contrast Medium in an MRI Machine

Abstract

In this study, Nickel Zinc Ferrite was prepared using the co-precipitation method according to the chemical formula Ni1-xZnxFe2O4, where the values of (x = 0,0.1,0.3,0.5,0.7,0.9) respectively, the structural and magnetic properties were studied through X-ray diffraction spectroscopy. FESEM showed the porosity and distribution of the homogeneous nanoparticles roughly, also its particle size. The vibration sample Magnetometer (VSM)was used to study magnetic properties, and the Fourier transform infrared (FTIR) spectra were measured in the range of 400-4000 cm−1. Magnetic nanoparticles effect on contrast factors in magnetic resonance imaging (MRI) images was studied, it showed Good and robust imaging technique for diagnosis and post-treatment evaluation for a wide range of diseases. MRI contrast can be enhanced by using negative or positive contrast agents, resulting in clearer (T1-weighted) or darker (T2-weighted) images, respectively, with super-magnetic nanoparticles yielding T2 contrast agents widely used in molecular imaging applications and cellular. As most of the work in this field focuses on the acquisition of biological species using nanoparticles, which in turn will improve the magnetic properties that lead to higher imaging.
