Abstract

Magnetic particle imaging?MPI?uses magnetic nanoparticles(MNPs) to generate signals, and there are already several commercial MNPs available for MPI. MPI guided magnetic hyperthermia (MH) has a huge application prospect in the precision treatment of tumor. It is of great significance for MPI-guided MH to find a kind of MNPs suitable for both MPI and MH. In this work, we first tested the heating efficiency of five kinds of commercial MNPs(Micromod for Perimag,Synomag-70,Synomag-50;Magnetic Insight for Vivotrax;Nanoeast for Mag3300)commonly used in MPI at 163kHz?8mT.Of these MNPs, Mag3300 has the best heating efficiency under fixed conditions. The further test showed that Mag3300 can be heated up to at least 41.2 ? . This shows the potential of Mag3300 for MPI-guided MH under this conditions.
