Synthesis of heterodimer radionuclide nanoparticles for magnetic resonance and single-photon emission computed tomography dual-modality imaging

Nanoscale. 2015 Feb 28;7(8):3392-5. doi: 10.1039/c4nr07255c.

Abstract

We report a facile synthesis of bifunctional Fe3O4-Ag(125)I heterodimers for use as dual-modality imaging agents in magnetic resonance (MR) and single-photon emission computed tomography (SPECT). We introduced (125)I, which is a clinically used radioisotope, as a SPECT reporter, into Fe3O4-Ag heterodimer nanoparticles to provide a new type of bifunctional contrast agent for MRI and SPECT imaging.
