Fluorescein surface-modified gadolinium oxide nanoparticles which were synthesized in triethylene glycol were nearly monodisperse in diameter and highly water-dispersible. These nanoparticles can be used as MRI contrast agent as well as optical imaging. This dual imaging capability will increase the possibility of an early observation of disease such as cancer. Magnetic Resonance Imaging (MRI) is primarily a noninvasive medical imaging technique used in radiology to visualize detailed internal structure and limited function of the body
