摘要：
The present invention relates to a magnetic resonance imaging (MRI) T1 contrast agent composition including T1 contrast material coated on the surface of a nanoparticle support. The MRI T1 contrast agent composition of the present invention has excellent T1 spin magnetic relaxation effects by modifying the paramagnetic T1 contrast material on the nanoparticle support having a certain diameter such that the paramagnetic T1 contrast material has a certain thickness or less, and thereby remarkably increasing the surface-to-volume ratio of the T1 contrast material. The present invention provides more precise and clear T1 positive contrast images, and is thus useful for highly reliable image diagnosis.
