FDA-approved iron oxide nanocrystals (IONs) as negative magnetic resonance imaging (MRI) contrast agents are encountering challenges because of their low relaxation rate and coherent ferromagnetism. Although metal doping has been found as an efficient way to improve the magnetic property and MRI contrast performance, the systemic mechanism has been rarely discussed.
