Abstract
The present invention relates to a magnetic resonance imaging (MRI) contrast agent, particularly an MRI contrast agent derived from nanoparticle that is porous first metal-doped second metal oxide nanoparticle with a central cavity, and a method for producing the same. The MEI contrast agent made in accordance with the present invention can be used not only as a drug-delivery agent for therapy but also as an MRI contrast agent for diagnosis.
