PREPARATION OF EXTREMELY SMALL AND UNIFORM SIZED, IRON OXIDE-BASED PARAMAGNETIC OR PSEUDO-PARAMAGNETIC NANOPARTICLES AND MRI T1 CONTRAST AGENTS USING THE SAME

摘要

Provided are a preparation method of iron oxide-based paramagnetic or pseudo-paramagnetic nanoparticles, iron oxide-based nanoparticles prepared by the same, and a T1 contrast agent including the same. More particularly, the disclosure describes a method for preparation of iron oxide nanoparticles having a extremely small and uniform size of 4nm or less based on thermal decomposition of iron oleate complex, iron oxide-based paramagnetic or pseudo-paramagnetic nanoparticles prepared by the same, and a Tl contrast agent including iron oxide-based paramagnetic or pseudo-paramagnetic nanoparticles.
