Synthesis of ⁶⁸Ga Core-doped Iron Oxide Nanoparticles for Dual Positron Emission Tomography /(T₁)Magnetic Resonance Imaging

Here, we present a protocol to obtain ⁶⁸Ga core-doped iron oxide nanoparticles via fast microwave-driven synthesis. The methodology renders PET/(T₁)MRI nanoparticles with radiolabeling efficiencies higher than 90% and radiochemical purity of 99% in a 20-min synthesis.
