Cellular imaging is an important and growing field in magnetic resonance. The ability to non-invasively detect the trafficking and accumulation of cells in vivo has broad implications for both a better understanding of biological processes and the development of novel treatments for numerous conditions. Here explore using post processing techniques called Phase map cross-correlation Detection and Quantification or PDQ for detection and quantification of single MPIO-labeled cells in vivo. PDQ uses phase information to calculate a magnetic dipole moment for each detected cell. This information can be used to correlate labeled cell between serial scans and imaging methods.
