| contents | Abstract: Due to the effect of magnetic nanoparticles on enhancing the quality and effectiveness of magnetic resonance imaging (MRI) in detecting inflamed tissues, the use of cobalt-zinc ferrite nanoparticles with dextran surface coating is investigated to improve the quality of images in this work. In this regard, magnetic cobalt-zinc ferrite nanoparticles are synthesized by the heat treatment method by adding different molar percentages of cobalt to zinc ferrite nanoparticles (CoxZn1xFe2O4). Also, the XRD, SEM, and VSM techniques are used to investigate the structural properties and the magnitude of magnetization of the synthesized nanoparticles. These results show that the magnetic saturation (and consequently the affinity towards the superparamagnetic behavior) of the synthesized nanoparticles increased with increase in cobalt concentration. Also, analysis of these results shows that the received MRI-signals (and thus image quality) are increased, when the relaxation time (T2) of these nanoparticles increases. 2021, Pleiades Publishing, Ltd. |
