Magnetic particle imaging (MPI) is an emerging medical imaging technique that could be a safer alternative to X-ray and CT using iodinated contrast agents, especially for patients with chronic kidney disease. Here we describe the overall technique, detail the latest advances in MPI theory, and discuss the optimal nanoparticle characteristics for MPI. We also show images taken using our latest MPI hardware, demonstrating MPI's already superb contrast and high sensitivity.
