Webinar: The Basics of Magnetic Particle Imaging

Recorded Presentation Here

This presentation will introduce a ground-breaking, next generation imaging technology called magnetic particle imaging (MPI). We will review the basic theory behind MPI along with current and future application opportunities.

Webinar: Preclinical Applications in Magnetic Particle Imaging

Recorded Presentation Here

This presentation will introduce magnetic particle imaging (MPI) and current applications in preclinical imaging. MPI is the first molecular imaging technique simultaneously capable of: nanomolar sensitivity, absolute quantitation, resolution independent of depth, and with tracer detection from weeks to months. MPI is complementary to existing molecular imaging techniques, giving scientists a new versatile tool to accelerate cancer, infectious disease, cell tracking, and vascular research.

Webinar: Nanoparticle Development for Magnetic Particle Imaging Applications

Recorded Presentation Here

MPI is a revolutionary technique for imaging iron oxide tracers with high sensitivity and contrast. This presentation will be co-hosted by Magnetic Insight and LodeSpin Labs.

LodeSpin Labs is developing a suite of high-performance MPI-optimized nanoparticles. These unique nanoparticles start as iron oxide cores for maximum SNR and resolution. Added functional, biocompatible coatings extend blood circulation and support conjugation chemistry for a variety of applications. LS-008, LodeSpins Lab’s blood pool tracer, circulates for hours in mice, greatly enhancing the MPI imaging window and improving SNR and resolution compared with standard SPIO tracers.

Additionally, Magnetic Insight will discuss the versatility of available SPIO’s to support applications in cell tracking, functional targeting and interventional imaging.

June 8, 2012. A big obstacle to developing stem cell therapies is being able to visualize the cells inside the body. This will be critical to confirm that the stem cells are targeted to the right place and are providing therapeutic benefit. Current imaging technology is not adequate for tracking stem cells in vivo.
